[invader-resource] Input paths without extension will always be checked for font/unicode_string_list/hud_message_text even when making bitmaps and sounds resource files.

Currently it is required that input lists for making loc.map contain no extensions, and the correct tags will be checked for in order.
It turns out that if your input lists for bitmaps.map and sounds.map contain no extensions and you pass -T sounds, invader-resource will still look for font/unicode_string_list/hud_message_text tags when creating those files.

What if it was changed to just use extensions in the input anyway for loc, like bitmaps and sounds?

There are also issues with / and \ in the lists, only \ is supported while / causes odd inconstant breakage.
