Before initial commit
=====================

* fixed bug in OPC.Genheader function. If new option is added in OPM, but not added in OPC, compiler was crashing. Simple ELSE fixed the problem.

* par file is not necessary by default (there is a command line argument for that, and defaultTarget is set in OPM.Mod, version.Mod and architecture.Mod) 

* external compiler is called by default. added options to just generate the output, and not call external compiler or assembler.

* OBERON variable always contains current directory path by default (changes in Kernel.Mod, added oocStrings dependency to it), as well as installed default libraries sym files path.
