Prezto plugins with be supported once I have time to finish #39. If no .plugin.zsh is found, it will source all *.zsh files, including Pezto's init.zsh

/cc @sharat87 Close please

init.zsh should be the only sourced file in case of prezto. that's what I meant by the integration.

Okay then, I'll add init.zsh to the loading logic.

I have just merged @midraal's pull request. Antigen now loads init.zsh if present, after first checking for a *.plugin.zsh.

But I think there is more to prezto's modules than that. I don't completely understand what prezto does, but I think the functions directory under the modules is added $fpath. Not sure though, need to look deeper as it seems prezto doesn't document its module structure.

I guess this is closed?

I planned to close it after adding tests for this functionality. But it probably should be tracked elsewhere anyway.
