gis may break Python help() modules command

[Karen Tracey]

This is similar to #5743 and perhaps could use a similar approach to fix?

Patch to raise different exception that allows Python's help to finish.

[Malcolm Tredinnick]

(In [8727]) Fixed #8680 -- Changed a couple of GEOExceptions to Python's RuntimeError so
that help() works. Without this change, even if you didn't use the gis stuff,
just using Python 2.5's help() system would crash when searching for model
names.

[Malcolm Tredinnick]

As noted in #5743, our policy is not to break help() for everybody just because we're installed, so this had to be fixed. There's a full explanation in the earlier tickets (where people were playing "why is Malcolm so dumb he can't understand this" and using sock puppets to teach me the way forwards).

Justin: I somewhat arbitrarily chose RuntimeError (the choices are RuntimeError and ImportError), but if you want to make a subclass of GEOSException and RuntimeError because you really want to be able to catch the former, go for it.

[Malcolm Tredinnick]

(In [8728]) Changed [8727] to use ImportError, which seems to actually work. Not sure what
I was smoking when I tested this 10 minutes ago. Refs #8680. Thanks to gkelly
for cleaning up after me.
