*	py: Initialise loaded_module map in rt_init.	Damien George	2014-01-22
\| \| \| \| \|	STM port crashes without this re-init. There should not be any state in the core py/ code that relies on pre-initialised data.
*	Make VM stack grow upwards, and so no reversed args arrays.	Damien George	2014-01-18
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Change state layout in VM so the stack starts at state[0] and grows upwards. Locals are at the top end of the state and number downwards. This cleans up a lot of the interface connecting the VM to C: now all functions that take an array of Micro Python objects are in order (ie no longer in reverse). Also clean up C API with keyword arguments (call_n and call_n_kw replaced with single call method that takes keyword arguments). And now make_new takes keyword arguments. emitnative.c has not yet been changed to comply with the new order of stack layout.

*	Split qstr into pools, and put initial pool in ROM.	Damien George	2014-01-04
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Qstr's are now split into a linked-list of qstr pools. This has 2 benefits: the first pool can be in ROM (huge benefit, since we no longer use RAM for the core qstrs), and subsequent pools use m_new for the next pool instead of m_renew (thus avoiding a huge single table for all the qstrs). Still would be better to use a hash table, but this scheme takes us part of the way (eventually convert the pools to hash tables). Also fixed bug with import. Also improved the way the module code is referenced (not magic number 1 anymore).
*	Basic implementation of import.	Damien George	2014-01-03
\| \| \| \| \| \|	import works for simple cases. Still work to do on finding the right script, and setting globals/locals correctly when running an imported function.
*	Change object representation from 1 big union to individual structs.	Damien	2013-12-21
\| \| \| \| \| \| \| \| \| \|	A big change. Micro Python objects are allocated as individual structs with the first element being a pointer to the type information (which is itself an object). This scheme follows CPython. Much more flexible, not necessarily slower, uses same heap memory, and can allocate objects statically. Also change name prefix, from py_ to mp_ (mp for Micro Python).
