Initial implementation search exclusion using project-based view setting.
Remove an incorrect assignment.
Switch to global view state instead of project-based one and also limit it to ten globs.
Fix JSLint error for extra trailing whitespaces.
Merge remote-tracking branch 'origin' into rlim/search-exclusions
First pass at UI for Find in Files exclusion filters. Not wired up to
seach implementation or prefs yet.

Changes the search bar to use ModalBar's autoClose behavior; no longer
assumes its code is the only thing to ever close the bar. Adds a new API to
ModalBar to allow the search bar to be 'locked open' when it would normally
close, as Find in Files needs for its no-results state and when the filter
editor dialog is open.

* origin/rlim/search-exclusions:
  Fix JSLint error for extra trailing whitespaces.
  Switch to global view state instead of project-based one and also limit it to ten globs.
  Remove an incorrect assignment.
  Initial implementation search exclusion using project-based view setting.
Wire up file exclusion UI to Find in Files search code & preferences.
Centralize code in FileFilters module. Switch prefs from single set of at
most 10 globs to an MRU list of at most 10 separate filters, each of which
is an unlimited set of globs. Properly update dropdown UI when editing
dialog is dismissed
Hoist out a generic DropdownButton widget from CSSInlineEditor, and use it
in FileFiters picker UI also, replacing the <select> element it used before.

Further enhance ModalBar to accept focus going to popup elements outside
its DOM hierarchy if they point back to the ModalBar as the popup's opener.
File exclusions usability improvements:
- Automatically add ** prefix and/or suffix in most cases
- Link to real docs page on wiki
- Show full filter set in picker button's tooltip
Fix bug that snuck into last FileFilters commit at last minute.
Small starter set of unit tests for FileFilters auto-prefix/suffix behavior.

Also fix whitespace JSLint glitch in unrelated unit-test file.
Simplify file exclusions UI & prefs after discussion in #7015: single
filter with no MRU history, and a simple edit button to bring up the
dialog.

Also ensure focus goes back to search field after dismissing filter-edit
dialog, per @RaymondLim's suggestion.
Basic UI integration tests for Find in Files filtering.

Fix race condition bug in ProjectManager where getAllFiles() can get stuck
returning list from previous project, if someone calls it in the middle of
async project-switching process. Doesn't seem to happen easily in normal
usage, but unit tests hit this when you call loadProjectInTestWindow(),
switching from the default project (usually Brackets src) to the test
projct quickly.
Merge remote-tracking branch 'origin/master' into pflynn/search-exclusions

* origin/master: (35 commits)
  redraw tree after cancelling node add operation
  Save side bar visibility immediately when not in resizing.
  code review comments. change frameNavigated handling from one to on to handling page navigation within the current project.
  Track performance impact of user viewstate loading
  Updated nls/README.md Step 3 to correspond with the new location of LOCALE_* entries
  Address review comments.
  Better order
  Actually set the USE_TAB_CHAR pref when it needs to be set.
  Set project root path to the project layer immediately after loading the project so that project tree (expanded/collapsed) states can be restored. Explicitly provide project root foler as layer ID so that new project-based keys can be created before recording view states in those keys. Migrate project base url that I missed to convert since it is also one of the old preferences that uses the prefix with the project root path as keys.
  Code review fixes
  sprint 36 - czech language update
  Inject remote functions earlier after frameNavigated instead of loadEventFired
  Add Michael Hernandez to the whitelist.
  Remove .livehtml flag
  Both variable declarations at the same place
  safer check for jquery object
  add comment about why important must be used
  Fix PreferencesManager test.
  Use a variable for the proper string
  Don't start firing preference change events until appReady.

Simplify file-exclusion filter syntax so we can use plain regexps instead
of globmatch, for a 100x speedup. With lots of unit tests for the new
glob-matching engine.
Fix bug when clearing filter: move trimming back to editFilter() so we
reliably detect when filter is blank. (Also fixes potential display bugs
when there are empty lines within a non-empty filter).
