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.
