x11-wm/i3-gaps: New package

A popular clone[1] of the improved dynamic tiling window manager i3
which supports gaps and few additional features[2]. There are several
ebuilds already in user overlays available[3][4][5]. Ebuild taken from
oboeverlay, improved by me. The original ebuild is probably the original
x11-wm/i3.
