Add a whole new set of combining diacritics

Including grave, accute, cedilla, circumflex, caron, tilde, ring,
breve, and many combined symbols using these. Moreover:
- Added the missing capital ß
- Added dotless i and j
- Added closing double quotes
- Replaced manual symbols with combined ones (improves consistency)
- Redesigned V, U, and Y.
- Switched to small dot (75x75) for almost all diacritics
- Added top/bottom anchors and marks for glyphs and diacritics
- Left positioning of diacritics to Fontforge (generated)

This commit is a result of the encouragement I received from the
wonderful people on Lemmy.
