Add the TravisCI build status badge to the README
Add development dependencies to the Travis config

I am hoping that this will resolve the problem with building native
extensions in the Travis CI server.

Fix Travis CI failure
Remove a semi-colon accidentally added to README
Removing apt-get dependencies

I think that I misunderstood the Travis build errors, and that the
problem with compiling BigDecimal was actually only limited to
Ruby1.8, and that the additional apt-get dev package installations
maybe not be necessary.
Update mocha require statement

Deprecation message indicates that this is now the correct way to
require mocha.
Remove the bigdecimal gem dependency

This does not seem to be used in the existing source code, so I am
going to try out removing it. It seems to be causing an error during
TravisCI execution, and this should fix it.
Add git config commands to the test runner

This will ensure that the cloned repositories will have user and email
configured, and not depend upon those values being configured for
either the user or the system where the test is being run.
Exclude metric_fu dependency based on ruby version

metric_fu includes the can gem which will not work with Ruby1.8.
By excluding it for 1.8 builds, then we can test the gem under Ruby1.8
with TravisCI.
