Much improved date handling in searches and autocomplete

Browse Source 
Fixes #338, Dates in search window should be converted to UTC before searching
Addresses #220, Add a more friendly way to enter dates in search window and accessDate field

- Unless passed a full datetime, the search system automatically parses the string with strToDate(), so one can search for an accessDate, etc., using a freeform phrase. It will use the SQL parts where available and also search for remaining words individually, so "November 6, 2006" will find '2006-10-06 Nov. 6 2006' and "Summer 2006" will find '2006-00-00 Summer 2006". It will also properly handle SQL parts, so "August 2006" in the is/isNot operator will use "LIKE '2006-08-__'" (underscore being the single-character wildcard) and isBefore will use '2006-08-00'

- Stored UTC dates are converted to localtime in the search system when searching on just a date part, since otherwise searching for a local date with a UTC timestamp after midnight would be unsuccessful

- Date field autocomplete is now disabled in the search dialog, but on the off-chance that it's used somewhere, the autocomplete will now return just the user part of a multipart date field

- Access date autocomplete only returns date, not datetime

- Fix for Date Added and Date Modified showing as UTC

- Date.isSQLDateTime()


Known issues:

- accessDate field in metadata pane still requires SQL format

- Proper parsing of search dates with no years (e.g. searching for "August 25") depends on #389, "Date.strToDate() should return available parts even if no year"
