This allows to pass java options to the jgit command line executable
by setting the environment variable "java_args", e.g.

$ java_args="-Xmx8g" jgit log

This also includes a change to generating the jgit CLI jar. Shading is
no longer possible because it breaks the signature of BouncyCastle.
Instead, the Spring Boot Loader Maven plug-in is now used to generate an
executable jar.

jgit.sh was concatenating classpath entries with ":". On Windows systems
using "Git for Windows" this caused problems when JGIT_CLASSPATH was set.

Find out whether we are running on a platform which name starts with
"MINGW" ("Git for Windows" sets this) and use ";" as classpath
separator in this case.

For some obscure reason the platform encodng in Java on Macs
is MacRoman. OS X used UTF-8 as the default encoding so set
the encoding property in jgit.sh.

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

If the command is either `diff` or `log`, there is often a lot of
lines of output. Run these commands through $GIT_PAGER, $PAGER, or
`less` in order to make it easier to browse the output on a terminal.

Drop our simple and stupid jgit.sh and instead rely upon Maven
for the command line based build.  Maven is relatively simple to
download and install, and doesn't require the entire Eclipse IDE.

To avoid too much refactoring of the current code we reuse the
existing src/ directory within each plugin, and treat each of
the existing OSGI bundles as one Maven artifact.

The command line wrapper jgit.sh no longer works in the uncompiled
state, as we don't know where to obtain our JSch or args4j from.
Developers will now need to compile it with `mvn package`, or run
our Main class from within an IDE which has the proper classpath.
