ad1bac63f7 tests/string-format: Add test for formatting ints with float format. 
Fail currently.

929a675a3d Change test scripts to use python3; bytecode tests use python3.4. 
I upgraded to Python 3.4.0, so needed to make these changes.  Hopefully
the tests still run with Python 3.3.x (the scripts use python3 so are
agnostic as to the subversion).

Bytecode tests are tightly coupled to the Python version, and now some
fail against Python 3.4.

baf6f14deb Enhance str.format support 
This adds support for almost everything (the comma isn't currently
supported).

The "unspecified" type with floats also doesn't behave exactly like
python.

Tested under unix with float and double

e44d26ae0c py: Implement __getattr__. 
It's not completely satisfactory, because a failed call to __getattr__
should not raise an exception.

__setattr__ could be implemented, but it would slow down all stores to a
user created object.  Need to implement some caching system.

Don't store final, failing value to the loop variable.  This fix also
makes for .. range a bit more efficient, as it uses less store/load

0c904df8e6 vm: Save current active exception on opening new try block. 
Required to reraise correct exceptions in except block, regardless if more
try blocks with active exceptions happen in the same except block.

P.S. This "automagic reraise" appears to be quite wasteful feature of Python
- we need to save pending exception just in case it *might* be reraised.
Instead, programmer could explcitly capture exception to a variable using
"except ... as var", and reraise that. So, consider disabling argless raise
support as an optimization.

__bool__() and __len__() are just the same as __neg__() or __invert__(),

type->unary_op() is just the right choice for this short of adding
standalone virtual method(s) to already big mp_obj_type_t structure.
