Map local to remote directories. (specific upload locations)

[TimVosch]

Hey, I added support to map local directories to remote directories.

For example, if I have a folder build and I want it to upload to my remote index instead of a build folder I'd do:

"directorymap": {
        "build": ""
    }

If I'd want to map my local test folder to a remote beta folder, i can do:

"directorymap": {
        "test": "beta"
    }

When you select local to remote and then directory test it will automatically upload to folder beta instead of test if this is specified in the directorymap

I just realized it curently only works if you upload the whole directory.

If I have dist mapped to build and I where to upload a folder dist/css then it would still upload as dist/css and not build/css. This is not hard to change. I'll add it once I have some time.
