Command line options match the C implementation of `git blame` as
closely as possible, making for a pretty complete tool.

This merge command accepts the merge strategy as option and uses the
resolve strategy as default. It expects exactly one other
revision which is merged with current head.

The Checkout command line command was added to JGit but it wasn't
registered in the list of available commands.
Additionally, the 'force' option was named '---force' (triple '-').

Implementation delegates all work to the AddCommand class and,
therefore, supports only those options currently supported by the
AddCommand which means: --update and the filepattern... arguments.

When working on a difference algorithm's implementation, its generally
more important to care about how it behaves on real-world inputs than
it does on fake inputs created for unit test cases. Run each
implementation against a number of real-world repositories, looking at
changes between files in each commit. This gives a better picture of
how a particular algorithm performs.
This test suite run against JGit and linux-2.6 with the current
available algorithms shows HistogramDiff always out-performs
MyersDiff, and by a wide margin on the linux-2.6 sources. As
HistogramDiff has similar output properties as PatienceDiff, the
resulting edits are probably also more human-readable. These test
results show that HistogramDiff is a good choice for the default
implementation, and also show that PatienceDiff isn't worth keeping.

This is the test suite I was using to help understand why we had
such a high collision rate with RawTextComparator, and to select
a replacement function.
Since its not something we will run very often, lets make it a
program in the debug package rather than a JUnit test. This way
we can run it on demand against any corpus of files we choose,
but we aren't bottlenecking our daily builds running tests with
no assertions.
Adding a new hash function to this suite is simple, just define
a new instance member of type "Hash" with the logic applied to
the region passed in.

This is a horribly crude application, it doesn't even verify that
the object its dumping is delta encoded. Its method of getting the
delta is pretty abusive to the public PackWriter API, because right
now we don't want to expose the real internal low-level methods
actually required to do this.

The commit command is added using the new Git class. Currently
this supports only the author and commit-message option.

The new plugin contains the bulk of the logic to scan a Git repository,
and query IPZilla, in order to produce an XML formatted IP log for the
requested revision of any Git based project. This plugin is suitable
for embedding into a servlet container, or into the Eclipse workbench.
The command line pgm package knows how to invoke this plugin through
the eclipse-iplog subcommand, permitting storage of the resulting
log as a local XML file.

This way we depend upon the MANIFEST.MF to define our classpath
and our build will act more like any other OSGI bundle build.

This removes one of the few remaining dependencies on AWTAuthenticator
from the core library. For the most part the interface is identical to
the prior main method. The jgit-pgm Main class already sets up the
HTTP proxy and authenticator for us, so we don't need to do that in
our new run method.
