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.

Various changes:
...
(1) New lua compatibility bindings, including select() and math functions
(2) fix some VM bugs
(3) fix some table bugs, and attempt to restore metatable functionality.

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.

Add new built-in function type() that returns the name of the type of
...
the given value as a string. Includes test case.

Refactor call stack and its use throughout. CallFrame now does all bytecode processing, and the callframe is reinitialized anytime something might have changed, like a function call.
