Pagination, readable error messages to user, syntax highlighting started.

Pagination now works. Temporary hardcoded 10 pastes per page, will be put

From now user will receive readable error message if error occured.

Started to work on syntax highlighting, tried to make lexers detection
work but apparently to no avail.
