a1115b2 adds backend support for varibles and code generation, only lacks editor and gui sysems

[icewolfz]

Add better back end support for function type, maybe auto create code stub like other places if not one defined in the function list, also pass the code into the format function system to better format the code

[icewolfz]

Back end code systems now will handle code stubs for function type and if name is not defined in function list will create a code stub
Back end code for mixed type if the value is wrapped in (: :) closure brakcets will create code stub if not in function and a valid identify
