John Ralls 3fd0762ae0 Move the HTML resources from gramps/plugins/webstuff to data and images
So that they're together with the other resources instead of in 
site-package/gramps. Aside from a better source and installation 
layout, this makes it easier to bundle them.

// TODO: in straight type-ahead mode (showResults: false), if noMatchingResults, dropdown appears after new match
// TODO: consider having options.mode (select, which replaces html select; combobox; suggest; others?)
// TODO: on resize (at least when wrapping within a table), the arrow is pushed down to the next line
// TODO: check for boundary/value problems (such as minChars of -1) and alert them
// TODO: add options for advanced paging template
// TODO: general cleanup and refactoring, commenting
// TODO: detailed Exception handling, logging
// TODO: FF2, up arrow from bottom has erratic scroll behavior (if multiple flexboxes on page)
// TODO: FF2 (and maybe IE7): if maxVisibleRows == number of returned rows, height is a bit off (maybe set to auto?)
// TODO: escape key only works from input box (this might be okay)
// TODO: make .getJSON parameters (object and callback function) configurable (e.g. when calling yahoo image search)
// TODO: escape key reverts to previous value (FF only?) (is this a good thing?)
// TEST: highlightMatches uses the case of whatever you typed in to replace the match string, which can look funny
// TEST: handle pageDown and pageUp keys when scrolling through results
// TEST: allow client-side paging (return all data initially, set paging:{pageSize:#}, and ensure maxCacheBytes is > 0)
// TEST: accept json object as first parameter to flexbox instead of page source, and have it work like a combobox
// TEST: implement no results template
// TEST: implement noResultsText and class
// TEST: watermark color should be configurable (and so should default input color)
// TEST: exception handling and alerts for common mistakes
// TEST: first example should use defaults ONLY
// TEST: add property initialValue, so you can set it when the flexbox loads
// TEST: handle hidden input value for form submissions
// TEST: how can we allow programmatically setting the field value (and therefore hidden value). add jquery function?
// TEST: use pageSize parameter as threshold to switch from no paging to paging based on results
// TEST: if you type in an input value that matches the html, it might display html code (try typing "class" in the input box)
// TEST: don't require all paging subprops (let default override)
// TEST: when tabbing from one ffb to another, the previous ffb results flash...
// TEST: IE7: when two non-paging ffbs right after each other, with only a clear-both div between them, the bottom ffb jumps down when selecting a value, then jumps back up on mouseover
// TEST: FF2, make sure we scroll to top before showing results (maxVisibleRows only)
// TEST: if maxVisibleRows is hiding the value the user types in to the input, scroll to that value (is this even possible?)
// TEST: make sure caching supports multiple ffbs uniquely
// TEST: when entering a number in the paging input box, the results are displayed twice
