[REQUEST] Customisable entries

[MikeSesketcharba]

Is your feature request related to a problem? Please describe.
I have a bunch of romhacks for the same game. Lemuroid identifies these games as copies (for example, both Mother 3 and Mother 3 Fan Translation are identified as the same game). I can't tell apart at a glance which game is which.

Describe the solution you'd like
For example, being able to change title and image for an entry in the rom list. Since I'm learning Japanese, I'd have マザー 3 for the one in Japanese, and "Mother 3" for the English translation.

Describe alternatives you've considered
Maybe a way to externally modify the metadata of each game. I have not done research on the topic yet.
