Remebers each Folder's settings for a separate File Filter

Right now, there's only one File Filter.  You can't right click on a folder for anything related to this right now.

What I propose is to have a separate File Filter for each folder.   So, when I'm in the root directory, all the file filters are working separately to bring me all the files I want to see from all folders in the root folder.  I don't have to keep hunting down the new files from a specific folder and then go back to root to commit the other files that I'm working on.

Example:

Let's say that folder War3Source-EVO/addons/sourcemod/translations/ has new files in it, but the root folder War3Source-EVO has all the other updated files.... I could put a File Filter on folder War3Source-EVO/addons/sourcemod/translations/ to display only new ws3*.txt files only.   When in root, I could see those new files and the changed files I wanted to commit from all the other sub folders.
