Allow negative coordinates in MonitorRules

Monitor/output position (-1, -1) remains as a single indicator value for autoconfigure layout.
Additionally, one minor comment typo is corrected.

Update wmenu-run name

switch to wmenu

bemenu is very bloated, turning itself into a library, which makes it
7489 SLOC.

wmenu on the other hand, looks suckless by default, and is only 2000
SLOC, which i also find alot nicer to use, since bemenu does nothing
to replicate the original dmenu feel.

Fix rule examples; minimize newbie surprises

Make example rules be actual EXAMPLES.
Now newcomers should not have to ask, "When I start firefox, nothing
happens. What is going on?"

Also clarified a minor typo and a consistency in spacing.
