File specific configuration command similar to ModuleInfo "string"

[GWRon]

For now BMK handles "ModuleInfo" in module files. But I think it would be nice if certain features are also available to "normal" source files.

Assume you do not want to use a module a module (needs install to BlitzMax/mods) but rather use it as normal source file. For now BMK/BCC only handle "ModuleInfo" (eg. ModuleInfo "CC_OPTS: -fexceptions"). BMK allows certain stuff (cc opts) in "custom.bmk". But this is then a global configuration, no "app individual" one.

Maybe we should introduce "FileInfo" which does a similar job - but on a file rather a complete module or globally (via custom.bmk).
