The check_memory and check_swap plugins on Windows were incorrectly
rounding the memory/swap measurements to the nearest unit prior to
calculating a percentage. This was causing imprecise percentage
values when the unit selected meant that the values in question had
few significant figures.

Adds check_memory which works like check_swap which has been updated to work like check_memory
Both sport a -u(nit) option with MB as default, like their linux versions.
A possible bug with all plugins having the -u(nit) option when using -u kB has been fixed. Don't use icinga to monitor you commodore though.
