- Bugfix: Macro expansion of strings would assert an internal error

- Bugfix: Macro expansion of strings would assert an internal error
  or a segfault due to a lacking '\0' in the expansion.
- Bugfix: Prevent buffer overflow in reallocation of macro expansion
  buffers.
- Bugfix: Wrc's version information was not passed as numerical to the
  preprocessor due to an error in the definition of the macro.
- Relaxed the newline constraint in global LANGUAGE statements, which
  was introduced in version 1.1.3, so that some fancy preprocessor
  constructs can work.
- Removed the gcc-style #line handling from the resource-parser to the
  resource-scanner so that it is possible to include files at any stage
  of the source, independent of the parser-state.
- Bugfix: Stringtables were not correctly searched for duplicates
  because the language comparison disregarded the sublanguage.
- Eliminated a repetitive warning when writing stringtables with zero
  length string entries. These are perfectly valid (but make no sense:-).
  Warnings are now only generated during parse in pedantic mode.
