Avoids need to call reset on it, and might help RPython to figure out that frame does not escape (making it more functional like this often helped in the past)

Introduction of AbstractObject without fields and classes.
Methods are not Arrays anymore to simplify and avoid use of 'object fields'.
Frames are not entirely implementation specific.

- clean out superficial comments
- added missing primitives

version the global dict: make the JIT assume that globals are rarely
changed at runtime and make it produce new machine code when they
change.

it always lead to two dict lookups instead of one

the computation of the key and the global lookup was reaaaaally
expensive

Most fields can be initialized on construction of the object and do not need to be changeable later

The classes were not put into the globals dictionary and got loaded more than once, which lead to the classes being not equal to each other.

first, _start_time in the primitve module would be frozen on translate time
and not set when the binary starts.

second, python random is not rpython, we use rrandom

for that, provide own raw_input.
also: crtl-d works now.

Let's try to have all theses things in one place, to reduce the differences between PySOM a RPySOM to a minimum.

RPython does not like sys.exit, so we emulate it using an Exit-Exception.
Also, we add a proper target file

- RPython does not support them, so we changed from the to module-level methods
