create a customized UserContextParser for user_stmt and user_scope
fix end_pos stuff for fast parser
start to remove user_stmt parsing
fix some colorama/pytest combo crazyness
flow syntax errors should still make it possible to add them to the parser (otherwise parser doesn't include all the code
allow for flows to also be very faulty
for loops are now parsed even if they are really faulty and don't end.
minor changes
implement user_scope search separately in UserContextParser
remove user_stmt and user_scope stuff - yes!
reenable check_user_statement in parser, that did the whole user names calculation
test fixing
user_position removed from Parser. yikes!
Remove UserContextParser again from docstring stuff, not really needed there. use a simpler solution
that test again...
