.bowerrc needs to be updated to use new bower repository

[catmanjan]

Bower no longer supports the herokuapp repository and so the compilation instructions no longer work

Need to change the repo in .bowerrc to https://registry.bower.io

[ciroppina]

lets provide an example ("core" module):

{
    "directory": "src/main/public/static/bower_components/",
	"timeout": 120000,
	"registry": {
		"search": [
		  "https://registry.bower.io"
		]
	}
}
