Update arcem to 1.00

Changes are

- New manual and new SourceForge page. Other documentation deprecated.
- Added project files for MS VC++, and fix warnings provoked by it.
- Further split of windowing/non-windowing functionality to aid division
  of architecture-independent files.
- Windows version made independent from Cygwin.
- Windows support imported from eQRD version. Features brought inline with
  other versions, including icon change, and same format for choices file.
- Entirety of build warnings fixed under GCC, including those that appeared
  from turning on harsh warning flags.
- General tidying.
- Makefile rearranged so that default Unix builds are more sensible.
- Support for running RISC OS, by Alex Macfarlane Smith and Peter Naulls
- Split of the windowing aspects of the code, to allow independent development.
- Some small speed ups.
- Source code tidying and warning fixes.
