corrected name spelling and added email to README.
Removed logback.xml from packed jar files

logback.xml was packaged inside of the jar file, which made gitminer
very unhappy when used as an embedded component that also required
logback.xml. Now it copies logback.xml to the target directory. Either
copy it to the base directory if you want color or use the -l flag
on the command line. For example:

    ./github.sh -c configuration.properties -l target/logback.xml

Added PropertyName.HASH for COMMIT and GRAVATAR

Before there wasn't a nice way to get these fields. Being as the hash
is the default identifier, we should have PropertyName.HASH.

Work around NullPointerException in PageIterator

I think the error actually arises from PageIterator in the GitHub java
SDK. This is a simple little workaround until I patch the other
library.

Updated to GovSciGraph 2.1.0. Renamed to GitMiner

This is a possibly breaking change, but it appears it works. I've
updated the code to use govscigraph 2.1.0 which tracks the 2.1.0
series of TinkerPop. This required some changes to various parts of
the code to ensure that we were using the updated package names.

The program was also renamed to gitminer.

A fix was applied for NullPointerExceptions at the end of execution.

Closes #32.

Updated to address GitHub URL changes

GitHub recently changed URLs to require https instead of http, this
fixes the code so we can pull repositories.

Also, added in some defaults for some of the properties within
repository loader. In the future the property code should be merged
with the property code from the main part of gitminer.
