Subject: * src/split.c (VERTICALLY): new define (VERTICALLY): likewise
 (split_frame): new argument 'pixels'. The current frame is split and resized
 to 'pixels' pixels. (v_split_frame): new argument 'pixels'. prototype
 updated. (h_split_frame): likewise

* src/actions.c (user_commands): hsplit, vsplit, and split take a
string argument.
(read_split): new function
(cmd_h_split): takes a ratio or number to determine how big the
frame split will be.
(cmd_v_split): likewise
