projects.html: Add filters for searching projects

This commit adds filters for filtering the projects based on
project work status, tags, difficulty level, initiatives and
collaborating projects, using angular.
Also, due to addition of new changes, the file length (i.e. line
count) got increased to 500+. Therefore, the coala module
directives are splitted and added a new folder named directives
that consists of all the app directives. Also, it makes the
project more understandable to users, that what all directives
does this project uses instead of scrolling down through the
large lines of code (if not splitted out).

Closes #559
