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.
