configuration, controller config,and cheat files

After farting around with x-ports "upload game configuration" code I got to thinking it'd be kinda sweet if the user could download controller configs and cheat settings as well. His code doesn't really save the config info which can be pretty useful when you have a bunch of keys mapped to the controller.

Then I got to thinking further. What if I CRC'ed the file and included the CRC as part of the filename and then included a bunch of those files with Atarixlbox in directories (configs, presets, cheats). Then if the program finds a match it can ask the user if he wants to use them. Well assuming I can get the CRC calculation code working.

I would also add and leave in this ability for the upload section. I'm also thinking of moving the up/down configuration into the options menu since it seems to make more sense to have it there.

As for the menu changes I was thinking about.... I'm gonna go ahead and do them since I'm getting no feedback.
