Allow for override of default config specific to rom file

[GoogleCodeExporter]

Describe your system:
 - Linux distribution: Gentoo 2008.0
 - Machine type: i686 (pentium 4, Nvidia 7600GT)
 - Mupen64Plus version: SVN (revision 481)
 - Plugins used: Rice Video, Blight Input

For visual artifacts, give:
- game name and CRC/MD5 hash (printed on console)
- description of the artifact (missing polygons, flashing, wrong colors, etc)

Describe the problem:

Seeing as some games work great with specific video plugins while they work
terribly with others, why not have mupen64plus generate a .romnameconfig
file inside the ~/.mupen64plus directory so that the user can override the
default settings if necessary?  This is very simple to implement on code
and only requires a check once (when the rom is loaded).  

Please provide any additional information below.
This problem occurred to me when playing Mario Tennis with Rice's Video
plugin (with several enhancements on) and Paper Mario.  I noticed several
visual artifacts and discovered that Glide64 will work better for these
games or even Rice's Video plugin with half of the filtering and
enhancements turned off.

This has been suggested before but it's really just a work-around and does not
address the core problem, which is that the video plugins do not accurately 
emulate
the N64's video system.  In the future we will be improving the video plugins, 
so the
need for a ROM-specific plugin setting will be diminished.
