Add ability to change system names (or other preferences via an .ini file)

[cautious-bread]

Just to be clear, I love that there are almost no settings in the UI itself - the less that a user can break, the better!
But I'd also like the ability to tweak a few things by setting them within an "ini file" on the SD card.

Some example are;

[ui-preferences]
system-list-allignment=centre # Align the list text to the left, centre or right.
system-header=true # Show the system name at the top when browsing the games list.

[system-names]
MD="Mega Drive" # Custom system names.

Just a thought for additional features.
Loving your work.
