Improve & bugfix modaction

This adds the parameters `mod` and `type` to `get_mod_log`. Tested with both username and `Redditor` object.

equality didn't work for `ModAction` because it doesn't have the variable `fullname`. But it has `mod_id36` instead which can be used to compare between two `ModAction`s.

For this testing I created and modded a new account named 'PyAPITestuser4' , the pswd for the acct is the same as usual.
