This module produces 6 icons:
["clock", "profile"] * ["black", "gray", "white"]
of which only 3 are needed: clock-gray, clock-white, profile-gray.
This patch removes the module and moves the "clock" and "profile"
icons into `skins.minerva.icons.images`. Since that module
does not inline SVG's, the additional cost of adding these icons,
which are loaded at startup, is minimal.
The editLocked.svg icon has also been edited to correct its color.
