4997800a76 make-traversal's optional argument is now ignored 
Recent changes eliminated it, but it seems better
(for backwards compatibility) to leave it there but
ignore it

39e4ac15e5 bring 'jump to definition' more in line with online check syntax 
That is, when right-clicking on an imported identifier, if the
file that has that identifier's definition is open and online
check syntax has completed, then offer a "jump to definition" menu
item that just jumps there with the already computed informtion.
If the file isn't open or online check syntax hasn't completed,
instead offer just to go to the file, without jumping to the definition

also
- things should generally work slightly better with submodules
- jumping to identifiers should do a better job with scrolling,
  specifically it should scroll so the jumped-to identifier is
  about 20% from the top of the window (unless it was already visible,
  in which case no scrolling should occur)

007d18d145 properly handle eof in the online expansion code 
It used to just kind of give up processing which, from the outside,
watching looked like

  (begin-for-syntax (custodian-shutdown-all (current-custodian)))

and so fell into that case in the code. Now, by explicitly raising
an exception, we get a more accurate response

18ad15c659 redex: fix `metafunction->pict' width correction for linebreaks 
The revised implementation is more clearly and directly expressed
in terms of table cells that span columns.

Also, avoid `panorama' by removing a useless `inset' that seems
likely to be the reason for the `panorama'.

Unix bitmaps to go with the new tests are missing; Robby plans to
add them.

5e20f51415 fix mark handling for impersonatored procedures to match docs 
Using an impersonator property to represent an application mark was
a bad choice. The property gets propagated, so it is also on any later
chaperone layer, and then things go bad: the docs say that special
treatment is triggered by supplying an argument to `impersonate-property',
but it was actually triggered by the chaperone having the property.

Change the implementation to match the documentation. Using an
impersonator property to supply the mark should be regarded as a hack,
but now the implementaiton is at least consistent with the documentaiton.

9621a58c4c change expansion of ->i to make renaming work better in check syntax 
Specifically, when expanding in the body of a dependent argument, put
the original variable for the dependened on field into that code, but
changing the expansion so that the binder becomes the original field's
x, not the x in the dependent declaration list.

This means that, for example, in this program:

(->i ([x any/c]
      [y (x) (begin x any/c)]
      [z (x) (begin x any/c)]) any)

the first x will be the binder and the other four now count as
bound occurrences.

Also, rip off Casey's redex check syntax tests to add tests

899a3279c2 add experimental support for "phaseless" modules 
The intent is to support phase-crossing data such as the `exn:fail:syntax'
structure type that is instantiaed by macros and recognized by contexts
that use `eval' or `expand'. Phaseless modules are highly constrained,
however, to avoid new cross-phase channels, and a module is inferred to
be phaseless when it fits syntactic constraints.

I've adjusted `racket/kernel' and improved its documentation a little
so that it can be used to implement a phaseless module (which can
import only from other phaseless modules).

This change also adds a `flags' field to the `mod' structure type
from `compiler/zo-structs'.

18c009276d fix up tests to reflect the module-lexer now behaves a little 
better wrt to its first result

That is, instead of just returning the string "#lang" it now
returns the actual text that was there (it was supposed to be
doing that all along and my recent commit fixed it, but I
missed the test cases)

b0343aa9f0 add a contract on the interaction between the module-lexer and the 
lexers it defers to

also, remove the checks in color.rkt in the framework (they are not
all covered by the added contract, but they mostly are and when they
aren't, most of those times are using the heavily tested racket-lexer)
