[fpc-pascal] alternative source format

[L505]

| i had in mind something like unified project format for all pascal's IDEs.

I think Pascal code and basic config files are a lot easier to read than XML and
all the tags. I think XML obfuscates the pascal code. With something like FPDOC,
XML can work well because there are very sparse tags (more text than tags).. so
it doesn't obfuscate the document.
