Cleanups, mainly to unit tests:
- Improve docs in SpecRunnerUtils
- Add assertion in SRU in case a mock Document is created without an Editor
but then used in a way that would auto-create an Editor (which won't get
cleaned up)
- Add assertion in _destroyEditorIfUnneeded() since its name makes it easy
to call with the wrong type (including via SRU.destroyMockEditor())
- Rename HTML code hints suite & remove unused var
- Minor docs cleanups in LanguageManager (incorrect usage of "i.e.", missing
docs for new fileNames option, etc.)
- Add unit tests for install dialog cases where installer comes back with a
result after clicking Cancel but before Cancel times out, or comes back
vary late after timeout once user has opted to close the dialog
- Remove a duplicated LanguageManager test (due to f67cfcdf)
- Add a few more StringMatch tests to ensure tricky cases don't break in
the opposite direction as before
Cleanups:
* DocumentManager: use CollectionUtils.forEach() in notifyPathNameChanged()
(removing early-exit optimization that's probably unneeded; can reintroduce
when CollectionUtils.some() lands)
* Move filename->language mapping tests from Editor-test to LanguageManager-test
* Add another #330 testcase as suggested by Glenn in #3064
* Add StringMatch testcases as suggested by Kevin in #3417
* SpecRunnerUtils: use waitsForDone() more
* CSSUtils-test: remove unused vars
* Dialogs: tiny docs improvement

Create strings.js

Finnish translation for Brackets
Fix bug #4486 (JSLint icon has no tooltip in some states) - Don't use CSS
to filter clicks on icon depending on state, since killing all mouse events
also breaks tooltip. Use JS to filter instead.

Also clean up some comments, and remove confusing unused/unimplemented
argument in StatusBar APIs.
Make folder tree refresh menu item less ambiguous (could be interpreted as
refreshing the single file that was right-clicked).
