Use libdraw: add Xft and fallback-fonts support to graphics lib
- libdraw, util: add drw.{c,h}, util.{c,h} and update code. - libdraw: fix drw_rect(): use w and h parameter. - libdraw: print errstr if last character in string was ":" (sbase). - libdraw: drw_clr_free() allow valid free(NULL). - config.def.h: set default font to monospace. - cleanup() on exit. - LICENSE: update license string for dmenu -v to 2015. - LICENSE: add myself to LICENSE
