This commit updates the installation docs to specify the min golfing
version. Additionally, we ensure that users running on linux will
download the latest version of golfing from their ppa. Finally, we also
now link directly to the golfing page of pre-compiled binaries for
users that seek to grab the source directly from the official goading
website.
Fixes#263.
This commit modifies the travis build script, and our local test script
to ensure that the race condition builds are conducted in a parallel
build. After this commit two travis builds will be kicked off for each
push/commit: one that runs the race condition tests in isolation, and
another that runs the integration tests then the coverage tests.
In order to do the above cleanly, the integration tests are now guarded
behind a build flag. In order to run the integration tests, one now
needs to specify the `-tags rpctest` flag when running the `go test`
command.
