LoveHate module shows same results on all user pages

There is an error in the logic of function lovehate_get_user_terms($uid = 0).

The function calls other functions that are $uid dependent, but does not pass the $uid variable. This causes the lovehate_get_all_terms() function to revert to the global $user->uid.

This patch correct that error by adding $uid as a variable to the following functions:

- lovehate_get_all_terms()
- lovehate_get_term_score()
