main: add _ to end of ttf names of roboto fonts

[maltejur]

This fixes #2766 by changing the ttf name of Roboto Regular from Roboto-Regular to Roboto-Regular_ with FontForge. This way, if the default system font is Roboto Regular, the FontLoader won't load the system font instead of the provideded one, which apparently leads to issues.

This doesn't seem like a clean solution to me, but it does the job and I have no idea what else could solve the issue.

have to be changed too. At this point it make sense to add a _ to all custom fonts to avoid it clashing with system fonts.

The filename stays the same, what I changed is the name of the font inside the ttf file.

Yeah probably a good idea. I'll also add that.

Sorry, didn't look properly at the diff :)
