Removed a few deprecated brands, including Mixer and Spectrum.
Updated iconography and brand colors to align with guidelines set by brands and to help increase visual accessibility. This will likely be the new style moving forward, so if you want to go back to brand color button backgrounds and solid white or black iconography, you'll need to do that on your own.
Added Facebook Messenger and Vimeo, please keep the suggestions coming for popular services that you believe should be included in the main branch for everyone by default.
