SeaMokey 2-42b8 and Thunderbird 45esr

Hi I've uploaded builds of SeaMonkey and Thunderbird built on the ESR 
branch using Bitwises Gecko code. They're 2 commits behind, so the 
readme and changelog haven't been updated to the same level as Firefox 
ESR and still require RUN!. They also only have the extra requirement of 
libvpx as well as possibly the nspr in the experimental repository 
(untested with the stable version of nspr, the experimental one was 
needed to build)
SeaMonkey is a special case as 2.42 was never released. I've backported 
a couple of patches and have more that don't apply, need to hunt through 
more bugs :) Both apps seem to run fine here though they seem to use 
more shared memory and SM is somewhat slow.
Not sure that Lightning will be automatically installed, it was here 
with an unpackaged binary. If needed I'll upload the XPI.
