eval - evaluate arbitrary perl code using actions

  URxvt.keysym.M-c: eval:selection_to_clipboard
  URxvt.keysym.M-v: eval:paste_clipboard
  URxvt.keysym.M-V: eval:paste_primary
  URxvt.keysym.M-Up: eval:scroll_up 1
  URxvt.keysym.M-Down: eval:scroll_down 1
  URxvt.keysym.M-Home: eval:scroll_to_top
  URxvt.keysym.M-End:  eval:scroll_to_bottom

Add support for evaluating arbitrary perl code using actions in keysym resources. If a keysym action takes the form "eval:STRING", the specified STRING is evaluated as a Perl expression. While the full urxvt API is available, the following methods are also provided for users' convenience, as they implement basic actions:

Scroll up or down by $count lines or pages.
Scroll to the top or bottom of the scrollback.
Copy the selection to the CLIPBOARD.
Paste the value of the PRIMARY or CLIPBOARD selection.
