Support local plugins about zpm-zsh

[fennecdjay]

Do you think the local plugin path has to be absolute ?
If not, I think the following behavior would address both #2 and #5:

• try to open path as regular file
  • on success treat path as a local plugin, else
• if path contains only one slash
  • host is github, else
• treat path as any git host

What is the intented behavior for local plugin?
is it enough add an entry to ~/.zpm/.plugin_list?

@fennecdjay Yes, path should be absolute, and the behavior should be the same for both, only there is no need for cloning/updating.

Done! Thank for your work @fennecdjay !
