In particular, .gitignore, *.go, *.sls and etcd.conf are files that
should not be marked as executable.
Tested: built it with hack/build-go.sh, called all binaries with
the -version flag to confirm they work.

Fixed up some scripts to be more robust. Changed the e2e test setup to use g1-small instances. Fixed up documentation to reflect the new script locations. Disabled the "curl | bash" cluster launch as it hasn't been well tested and doesn't include the cloudcfg tool yet.
