Improve bal tool with changes to class loading and packing jars from directory paths

[gayaldassanayake]

Purpose

• Move the classloading of tool jars to BLauncher.Main instead of the bal bash script. The loading is happening iff it is a tool command.
• Allow a tool creator to specify dependency jar paths using a gitignore type wild card pattern.
