feature suggestion

[merlinlcb]

just a feature suggestion, and maybe it exists and i just couldnt find it,
but a simple way to clear the cached scan would be really useful, i interrupted the scan on my drive and it absolutely tanked the software, it only knew where one nro was and even after i deleted said nro it would still only reflect that nro file in the menu, and it did not auto scan even with the feature enabled, i had to go clear the folder in the config folder on the sdcard in order to get the application back to a useable state
