Revert "Rename 'prefix' to 'umode'"

This reverts commit efde2954efd636a617702ee1aefb8b1247c9cc5b.

After some more consideration, we feel that referring to modes here is
misleading and confusing. Compromise by keeping the -m flag, but
changing the variable name back to 'prefix' and making clear in the help
message that quarg will match against the "channel membership prefix", a
term that is used in the Modern IRC Client Protocol specification [1]
