load prezto functions on plugin load

[ghost]

pmodloading the prezto module instead of sourcing init.zsh loads the module's functions, should improve issue #40.

[sharat87]

The pmodload function is defined by prezto. So, your implementation is fine for those who use prezto, but for those who don't, loading any plugin with a init.zsh will break the whole thing.

So, may be check for the existence of the pmodload function, and act accordingly. That is, if that function is available, we use your implementation, else, we just source it like it is done currently.

Could you make this change, so I'll merge it? Thank you!

this should work, not sure if there isn't a cleaner way to do it

Yes, thanks. Merged :)
