Copy the CHANGELOG from 3.4-working.
Rename the obt-4.0 and obrender-4.0 pkgconfig stuff to obt-3.5 and obrender-3.5

If an icon is the same as one in the cache, then it uses that one.
icons of different sizes (from the same client) are linked together into

so you only need one icon in memory for all your terminals now. ya!
