Conformity in the -g geometry handling.

Thanks to Yuri Karaban for suggesting this! These changes make -g correspond to <cols>x<rows> and honor it so non-tiling window managers can work with the size hints afterwards. It also adds a -i flag to force the window size. This is needed so -g keeps being useful in dwm.
