Browse Source 
* added functions

added:
  - get_cursor_position()
  - set_terminal_title(title string)

* implement term.get_cursor_position and term.set_terminal_title on unix

* Cleanup

* make x,y fields of term.Coord mutable

* fix vrepl compilation

* use more descriptive var names in term_test.v

* do not change the current terminal title in dumb terminals; do not test term.set_terminal_title outside of CI

* unix: in term.set_terminal_title, return true even for dumb terminals
