Fri Dec 19 17:13:39 PST 2014 Anton Vorontsov * X.L.Master: Add FixMaster layout modifier

This layout modifier is useful for the case if you desire to add a master pane that has fixed width (it's fixed even if there is just one window opened). Especially nice feature if you don't want to have too wide terminal in a master pane.

The layout is implemented as an addition to Master layout, so it reuses most of the code.
