abra binaries go from 19M to 7M when run under upx.

Start-up time is affected, it is slower. Is it noticeable tho?

➜ make build
➜ du -sh abra
19M	abra               
➜ time ./abra -v
abra version dev-f09ca6e
./abra -v  0.05s user 0.01s system 123% cpu 0.051 total

And:

set -ex

upx ./dist/abra_*/abra

I can get it to work, but I think it will affect the checksum generation.

Leaving off for now.

Checked again, abra from 20M -> 5.5M and kadabra to 4.6M! Really need to get around to this, especially for kadabra where startup times won't be really noticed at all due to being a server-side component.
