bug 1814: installer now only offers DB types which are available.

Abstracted a couple of hardcoded lists of mysql/pgsql checks and radio button creation to use a nice little array of names, installer funcs, and modules to check.
Only those DB types whose modules are present will be presented in the installer; if all are missing, we throw an error and list out all the possibilities we were looking for.
