Refactorized profile classes in order to better complain d20 system.
Wrote Armor Class method and some enhancements.
Moved all classes which provide structure for d20 system to the d20
package.
Generalised some classes, porting them to .profile package, in order to
keep Player class consistent without d20 structure.
Started writing proficiency system, for d20.
Completed Proficiency system, I hope.
Starting write Race interfaces
Races implemented rougly through copy/paste.
Will throw them when I'll be able to implement simulated multiple
inheritance in Java. Learning then...
Implementing races, but without multiple inheritance
