Add target to zip Matlab utility functions

Merge pull request #415 from sbesson/rebased/develop/dist-matlab

Create an ant target to distribute Matlab functions (rebased onto develop)
Fix the CLASSPATHs for the command line tools

Many of the classes for the command line tools are now in
scifio-tools.jar (instead of bio-formats.jar), so when the
'SCIFIO_DEVEL' environment variable is set we need to have
scifio-tools.jar on the CLASSPATH.

Noticed by Curtis Rueden.
