regex parsing

Results of parsing are continuosly appended to a list (decl and line).
caveat: parsing time is increased

Parsing is done via
* addDecoratedFunctions: calls WM's FunctionList
* old addDecoratedMacros:  WM's MacroList did not return line numbers. Deted
Extended Parsing
* new addDecoratedMacros: now returns line numbers for sorting and findcode
* addDecoratedConstants: searches for constant definitions
* addDecoratedStructure: searches for structure definitions and analyzes the containing elements.

addDecoratedConstants:
Definitions support static keyword

addDecoratedMacros: list decoration
* makro subtype after " : "
* makro parameters supported (bad coding)

addDecoratedStructure:
* structure definitions with surrounding {}
* supports all igor7 variables types for structure definitions
* unlike functions: in a structure "Name" of Variable is returned as it is more useful then "Type"
* Structure Variables are sorted alphanumerically if sort is checked
* main functions
** getStructureElements analyzes definitions inside structure/endstructure
** getVariableName analyzes name to return a in definitions like "a = b"

Helper Function
* trimArgument
** removes white spaces
** optionally changes listSparator

bugfix
abort added to getVariableName() in order to track down Nullstring Variable identification in structures
