Imported eabout, a small program that displays current EDE version, authors, contibutors, etc.

Added ProgramBare rule in Program.jam so there could be built plain (command-line) programs
and so they could be installed where other EDE programs resides.

New etip on FLTK1 code. Also, instead hardcoded tips, etip now uses fortune-like files
for tips. Ah yes, it is able to read fortune files too :)
