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.
MODULES variable added in order to specify directories where to look for source file. OBERON variable is not used by developer anymore, only MODULES variable.
error messages are now more descriptive (errors.Mod added)
help is now more descriptive
version module which defines the target and version string.
