USAGE:
1. Set individual usergroup permissions to turn on the ability to Bump/De-bump a thread for each usergroup (default is no ability to access this function).
2. Limit the number of times a thread can be bumped/de-bumped by each usergroup (in case you want normal users to be able to bump a thread only once, but for moderators it can be many times).

Database alterations carried out:
1. Adds columns 'bump' and 'debump' to your 'thread' table to count the number of times a thread has been bumped.
2. Adds columns 'bumpthreadspermissions' and 'bumpthreadslimit' to the 'usergroup' table to track who has permission to use the feature, and how many times per thread.

How change limit times per thread to limit times per day ?
Please help me!
