[xmonad] darcs patch: ManageHelpers, reduce duplicated code in predicates

[Ismael Carnales]

This patch adds a helper function isInProperty to reduce the
duplicated code in isFullscreen and isDialog of ManageHelpers.

Next step: making ManageDocks use this function or similar to avoid
more duplication.

Next next step: pushing this helpers (or in another way) into core, I
think that providing a common way of doing certain things helps
avoiding code duplication in Contrib.

byebye!

P.S: (this is my first code patch, so be gentle :) )
