WX: Add the ability to uninstall WADs from the game list

Simple quality-of-life addition that allows "uninstalling" WADs
(removing the corresponding installed title) from the NAND.

The option is only enabled when the WAD can be uninstalled

The motivation for this is actually to encourage proper usage of the
WAD launch feature (installing it to the NAND first), so we can
drop the "direct WAD title launch" hack.
