Various cleanups
Created by: akien-mga
- Adds .gitignore and removes obsolete files
- Removes PB and VisualC6 project files, if someone wants to build for Windows, they'd have to make new projects from scratch for modern IDEs anyway
- Convert some ISO-8859-1 files to UTF-8
I'm also thinking that jumpnbump.fbcon
and jumpnbump.svgalib
could be removed, they refer to (AFAIK) obsolete video modes in SDL2 (at least on my distro I get SDL ERROR: fbcon not available
). But I haven't done it in this PR as it would conflict with my other Makefile changes in #6.
