Update examples: minor changes, rename, update .gitignore

.gitignore, Makefile: add missing files, sort example filenames.
Makefile.FLTK: update and extend FLTKCONFIG definition examples.

Rename README.examples to README.txt (easier for Windows users).

README.txt: minor edits, fix link, remove trailing whitespace.
