Added bootstrap-tabdrop.js

This library makes sure that any tabs that don't fit are put into a single button (used in report.tpl)
This also includes a small bit of css, otherwise the library doesn't work.
More translation stuff

Fixed a small error in extract.sh
Added a line in language_nl.php and language_eng.php
(Note: this way of translations will be changed, I will be using gettext, which I've started applying, but it's not completely done)
Added some new functions, constants and edited index.php

index.php
Changed some urls
Added $smarty->display('functions.tpl'), which saves the hassle of having to include it in every template

functions.php
Added send_mail() function, which is just an easier way to send a mail with SwiftMailer
Added random_uuid() function, which is used to generate an UUID that is used in the reset password link a user receives
Added validate_form() function, which is used to validate certain forms (user, competencies, etc)

functions.tpl
Added print_alert function, which is just an easier way to print an alert
Added check_if_error function, which prints the inline error text in a form if there is an error
Big commit regarding views, but nothing really special

Views:
Changed a lot of small thing in template. Stuff like changing some function names, adding translatables or removing some small things what aren't needed anymore
Changed some security stuff and added reset password

Controllers:
Added reset_password() and reset_password_post() functions

Views:
Added reset_password.tpl, which is just a simple form where a user can enter his/her email
Added new_password.tpl, which is the form that is used to enter a new password
Changed a lot of stuff regarding the competency, department, user and role pages

Controllers:
Split up competency and competency group into two separate files
Changed return html('Error message') to header('Location: ' etc.) for the most part. All the post functions now do a proper redirect to their lists

Views:
All the templates for edit and create should now be equal to each other (regarding the errors and values at least)
Some small changes to controllers

Added some more validation to feedback.php and added saving selected competencies to session
Added a subtext to report, which displays the amount of people that have reviewed you
