* Added support for parsing/serializing specifiers for OpCast roughtly.. Doesn't have constraints on what specifiers beyond whats expected in global nspace scope..
* Minor adjustments to hashtable to avoid UE compile errors
* Make sure scanner.cpp is being made by bootstrap
Isolating large macros to their own directory (components/temp).
- Plan is to remove them soon with proper generation.
Added additional component files, separating the old data_structures header for a set of ast headers.
Header_end also had its inlines extracted out.
Necessary to complete the macro isolation.
ZPL parser dependencies were removed from the core library along with builder, its now generated in bootstrap as pare of making a gen_builder set of files.
Singleheader will be changed in next few commits to reflect this as well (By making builder deps and components a conditional option).
Tests are most likely all broken for now.
