Added function expand_escapes() which handles now escaping /EVAL and input
line if /SET expand_escapes is set. Supported escapes are \t, \r, \n, \e (ESC), \x (HEX, \x1b), \c (CTRL char, \cA), \000 (octal, \033) git-svn-id: http://svn.irssi.org/repos/irssi/trunk@1727 dbcabf3a-b0e7-0310-adc4-f8d773084564
