Support multipart/form-data form FILE for action

[gabrielstuff]

Currently the action mandrill only support same machine file sharing or URL.

This means that you either:

• share the same folder + authorization
• create a static server to share the file you want to share

What would be is, is to be able to :

• push binary content directly
• send FILE in the POST

thanks !

It appears that socialite-v0 support file, see: https://github.com/soixantecircuits/altruist/blob/master/actions/socialite.js where mandrill action does not.

Wouldn't be preferable to develop a functionality that parse the query and make sure that all action can accept:

• path
• URI
• base64 data
• FILE in multipart/form-data
• Binary
