more escapes & more compability:
cursor keys are handled in kpress according to the Application Mode (DECPAM). define & enum were renamed. tcursor() is now tmovecursor() which is more correct. tcpos() is now tcursor(), as DECSC is also supposed to save attributes. capnames are indicated whenever possible. Currently: alsamixer looks fine, totally usable. ncmpc is almost ok. emacs looks like shit.
