Removed lib/language since I'm using gettext now
Fixed some stupid mistakes I made in the create/update templates and fixed competency.tpl. Also fixed a small issue regarding duplicate emails in functions.php
Added DataTables library which is a library to easily add interactivity (ordering, filtering, etc) to tables
Implemented DataTables. This means that a few templates have an extra bit of JavaScript which enables the functions of DataTables.
Added a bit of code in config.php which detects the locale.
Made sure that the extras (previous and next button, etc) from DataTables get correct translations
Added some translations that I missed
Small change to add_row.js which probably improves readability
