Add some helper methods:
...
(1) getKeys() in LTable is now public. It provides a convenient interface
to access the table's elements from Java instead of Lua.
(2) LString.toInputStream produces an instance of InputStream from which
the string's bytes can be read.

Change LString to use an array of bytes instead of wrapping Java's String.
...
This brings our implementation more in line with regular C Lua.

Allow metatable operations on values of all types, and use the metatable
...
on strings as the string package, so that string functions can be called
with self (:) syntax. Autoload test case now inexplicably fails more,
but it was already broken.

New implementation for Lua tables. Does not use Vector or Hashtable, instead
...
uses plain Java arrays directly to keep heap allocation to a minimum.
Includes some unit tests that seem to indicate the basic operations are
correct. However, the following things are not implemented:
* Shrinking the capacity when elements are removed
* Optimal storage of each element in array vs. hash when entries are
added out of order. A junit test case is there for this.

optimization for tables that include sequential integral indices starting with 0.

commented out: a more sophisticated (but space-consuming) optimization
that accounts for arbitrary starting index, stride, and direction (increasing/decreasing).
commented out some table metatable stuff that was wrong. metatables
need to be implemented properly.

Rework the main API"s that implement the calling convention. Provide utility methods to get arguments that were supplied, and provide return values. Add a VM interface to clarify the relationship between the VM, things that call the VM, and things that are called by the VM. Make the code more closely aligned with the C++ version.

an arbitrary OutputStream and tabs are no longer printed at the end of
each line.
