new ckeditor 4.1 + codemirror plugin + langs + about
Updated lock file
Improved inheritance of Doctrine's FilesystemCache
Some minor changes with regard to CKeditor 4.1 / #263

- Added some config options for codemirror.
- Removed "About" (sorry @electrolinux. CKEditor is credited on the
about page, the [?]-button would just confuse noob-users)
- Removed an unneeded file. (it was duplicated, and we kept the one
that's used)
Updated CacheTest and some small refactorings on Cache. Work in progress.
Removed deprecated methods from Cache class
Updated scrutinizer config to check workings of current config
Merge branch 'master' into no-issue-docs-and-tests
Updated Codemirror to version 3.11.

The core files are now used from the ckeditor plugin, to prevent
duplicate files. Also added 'php' to editmode in Codemirror. Related to
#263.

Merge pull request #272 from mablae/master

Fix Form in SimpleForm Extension using Namespaced Twig Path
Expanding upon #272, should fix #268.

- templates now work from the template folder
- added some clarification to the docs to explain it.
- refactored out a `global $app`

@mablae I didn't know about namespaced templates in twig. Seems like a
cool feature, but in this case we actually _want_ twig to fall back to
the other folders, if it can't find the template. :-)
