Google Drive and Dropbox resolvers

[AltarBeastiful]

Changes necessary in Tomahawk to implement Google Drive and Dropbox resolvers.

To compile :

• Install taglib >= 1.8 from sources (http://taglib.github.io/)
• Additional dependencies : sparsehash

Features :

• Resolvers can register to signals of their config.ui dialog.

Usage : Add a connections field in the settings of the resolver containing the signals of the current widget.

{
    fields: [{
                name: "associateButton",
                widget: "associateButton",      
                connections : [{ 
                                  signal: "clicked()", 
                                  javascriptCallback: "resolver.associateClicked();" 
                              }]  
            }]
}

• Parse ID3 tag from stream asynchronously. JS resolvers can call readCloudFile to read the tags from a distant music file.
• Resolver can request a web page to be opened to the user (used for Oauth).
• Asynch and Sync post request in tomahawk.js
