v2.7.3
Added special case to make Yahoo+Chrome work better. That combination tends to use <p> instead of <div>, which messed up plaintext. This actually fixes a shortcoming in previous versions, as well as making tables work.
Added change item about new support for Icedove
Created grayscale-ish images for the disabled toolbar button rather than using the svg trick
Improved Mozilla button icon size compatibility
Prepping for release
