First draft of implentation of HttpGetTimeout.
Added wontConnect and wontRead Transports to test timeout.
Added .travis.yml

This may not work the first time, I'll probably push directly if it
isn't happy for some reason. Need to get it in there to see though.
Added doc.go in console/test/ to fix build
script/test.sh: make work with gvm in travis-ci
travis.yml: make sure code coverage tool exists
travis.yml: fixed install of go cover tool
cmd test: fixed to handle console connecting to DB

This isn't very ideal; the console command (and thus also the crawl
command, since it starts a console) does not currently allow injecting a
mock DB, so we need to create the test schema for these tests to work.
We may want to rework it some.
Implemented TestWontConnectTimeout and tested it.
Merge branch 'master' into HttpGetTimeout
Added test for stalling reads to TestTimeout function.
Couple doc reformatting issues corrected with this delta.
Changed gc_grace_seconds to 0 for segments

Was seeing inefficiency due to many leftover tombstones because the
grace period for deleted rows was too long and I was crawling the same
sites very quickly. See the changes themselves for further description
of this change.
README: added build status image
README: added godoc link

config: updated to deal with go-yaml sequence bug

I really wish there were a better way to do this. Basically, go-yaml has
a bug where it won't overwrite sequence values, it appends. I found this
when I configured an alternat cassandra host and it still tried to use
localhost.

Hopefully the go-yaml people fix it quickly enough (filed issue:
https://github.com/go-yaml/yaml/issues/48). I looked into doing it
myself and it was taking too long to figure out.

I tried using https://github.com/imdario/mergo to do a merging thing so
we're less likely to make any mistakes but it just plain didn't work.

Having spent too much time, I'm doing it the
quick-and-throughly-commented way and moving on with life. Unless anyone
has better ideas.
