dwarffortress script -complete overhaul

- all paths stored in variables so install scripts can easily "sed" them
- catching most common errors & send notification so user can see them even if not run by terminal
- provide simple gui to "setcap cap_sys_ptrace=eip"
- fixed "bug" so DwarfTherapist will run without root privilieges if cap_sys_ptrace=eip is set

tested with Mint 17, Debian wheezy and Arch
