Bug 1290014 - Move code from the FaviconGenerator class to the IconGenerator in the icons package. r=ahunt,Grisha
The FaviconGenerator is the last class in the old favicons package. As this class is only used by the IconGenerator let's move the code inside the new class and remove FaviconGenerator. MozReview-Commit-ID: 7NsJRGdoUWv --HG-- extra : rebase_source : 703b80560f47220d094de0049cd9b92f8cd524eb
