First work for spell checker support, issue #67 underlines misspelled
words (only English dictionary right now), but no way to correct them or
to add words to the dictionary yet.
No longer mark numbers as misspellings, tweaked inline annos
Fixes #71 by replacing showdown with pagedown.
Merge branch 'master' into spell
Add  preference, set by default to false, for now
Fixes #66 by locking a file while writing, and temporarily disabling poll watchers while a file is locked.
Fixed #72 by adding a ctag indexer (detects classes and functions) and adding a built-in completer for all built PHP functions (and there are a lot of those).
Bump version, update changelog
Update indexes
* Switches ACE from no-conflict mode to regular one (be sure to rerun
* install_deps.sh!)
* Adds support for "Tools:Fix", a generic infrastructure to run
* arbitrary commands that can "fix" code or text (e.g. fix a spelling
* mistake, offer thesaurus based word suggestions, rename a variable
* etc.). Fix is bound to `Command-Enter`/`Ctrl-Enter`
* Adds a fixer for the spell checker (furthering progress on #67)
* No longer analyzes all open files on editor open, but does so on
* demand.
Tiny spell checker fix, and spell check toggle command
