[feature request] Option to use REGEX to rename files.

[jcruiser89]

The file names change often and some mangas have extremely long names that do not display properly in manga reader apps. I would like a way to set the file name to just the chapter number or whatever i like by using regex to parse the downloaded file name and having the series name as a parameter that can be used.

ex. series name Berserk
chapter being downloaded is 55
by default it may do something like 57 - Berserk V7 Ch.55
I would like to be able to change that to just Ch.55 or Berserk Ch.55.

Another example is a manga called Kouryakuhon o Kushi Suru Saikyou no Mahoutsukai ~ to wa Iwa Senai Oreryuu Mao Tobatsu Saizen Ruuto~

Its way to long to display in any reader so I would just use the chapter number.

Its fine if this is a global feature, would be nice if it could be changed per favorite.
