- Changed the login idea
	- Now you need to give post,email & pass for accessing your
		account
	- Changed the input for post field in the Register.jsp
		- now it's a dropdown of currently available posts in 
			the system
		- a new post can be added via "add new post" button & 
			the Javascript code adds it
- TODO:
	- Test it please :(
	- It's too buggy even after you've implemented the filter
		- test the validity of those filters in case of servlets
		- multiple tabs
		- invalid accesses
