Version 0.6.3

I18n improvemtents, dependency upgraded, doc fixes, performance tweaks,
cleanups and refactorings - everything you would expect from a bugfix
release.
And of course bugfixes, bugfixes, bugfixes...
Elijah brought back merging subsequent wiki edits by the same author
into a single version to make notifications less noisy and the history
cleaner.

Thanks to perfectritone we now have install instructions for OSX and
aliaksandrb provided the basics for vagrant based development.

This will probably be the last bugfix release for the 0.6 series.
0.7 and thus rails 4.2 lay ahead of us. :)
