Fix wt

- Defaults wt's boost to 1.48 as that runs on 12.04 and 14.04
- See http://packages.ubuntu.com/search?keywords=libboost-dev

Closes #1007
Formatting: replaced tabs with 8 spaces, removed PostgreSQL workaround
Building boost from source, using g++ 4.8 to make it work on Ubuntu 12.04 and 14.04
Better support for new directory structure
Update yaml to better reflect new directory structure
Remove TESTDIRs that will always error

These are ones that have no linux-only tests we can run inside travis
Ensure new changes properly cancel unneeded tests
