This includes changes which greatly simplify the build system by
getting rid of the conditional support on Bash, when
Bash is needed for a succesful build anyway. Other changes
include using the "jar" binary (part of JDK) to manipulate jar's,
instead of the external unzip binary (not part of msysgit on
Windows). Issue 4052.

- If the submodule doesn't eixst yet, then submodule update is called
- If the submodule points at the right commit then nothing happens.
- If the submodule is pointed at any other commit, this script will attempt to rebase.
  - If the rebase fails (for any reason!) then the local HEAD is used rather than just switching to whatever upstream uses.

All automatic updating is disabled by default.
Set submodule.update=true in private.properties to enable.

Automatically run `git submodule init` and `git submodule update` when compiling to make sure submodules are all ok.

Always add all plugins the the main jar even if they are all up to date.
