use OlderOrSame_Date instead of Older_Date to compare date/time, to recompile files if the date/time is the same (using more accurate times would be useful)

On Windows:
- Items starting with -l are ignored
- Everything else is treated as an ASCII library file

On other platforms:
- Items starting with -l are treated as shared libraries
- Items containing a dot are treated as normal files and linked
- Other items are ignored

This allows one to use for example:

	import code from library "mylib_library"
	import code from library "-lmylib"

(where Clean System Files\mylib_library refers to mylib.dll or so).
The first entry is used on Windows; the second on non-Windows.

Create separate stages for optimising ABC and generating bytecode, so that the timestamps of these files differ for large projects

Previously an imported object file:
```
implementation module test.test

import code from "obj.o"
```

Would only search in the roots of the project paths. Now it will als
search in the test/ folder in the root.

Add EnvironmentByteCodePrelink and PrelinkByteCode options to prelink bytecode for use with the WebAssembly interpreter

in project files for modules in a directory write the directory once, instead of per module (to reduce problems caused by version control systems)

saveEnvironments (now saveEnvironmentsStupArg),
to reduce the number of GetFullApplicationPath calls in BatchBuild
