Subject: make thumbnail bindings configureable via config.h (#167)

this allows for configuring thumbnail mode mouse bindings similar to
image mode bindings.

however we can't put the thumbnails bindings into the existing buttons[]
array due to fallthrough. For example M3 would switch mode and then end
up selecting an image.

which is why thumbnail bindings have been put into it's own array
`buttons_tns[]` and `buttons[]` has been renamed to `buttons_img[]` for
consistency.

Closes: https://github.com/nsxiv/nsxiv/issues/131
