Files:
* Consistently have one (1) new line at EOF
(.gitignore, *.css, *.sh)
JSHint:
* Separate the common (general Wikimedia code conventions) from
the local more stricter rules (nice work!).
Maintenance:
* Use simplified $IP definition where getenv is only called once.
Based on http://git.io/ve-mw-36fc3b59-makeStaticLoader
JavaScript:
* Use the same closure in all files:
- No need for "undefined".
- One linebreak between license header and start of closure
(sometimes there were 1 or 2 empty lines).
- ext.uls.ime.js: No need for "document" (redundant in general,
but especially as it wasn't used anywhere in this file).
- Use "$, mw" for all ext.* modules (one of them used "mw, $").
