Fix for Issues #8285 and #8284

[markodjurovic]

• For issue Issues with starting embedded server #8285 support for legacy is removed. Cause of the issue is that that DB is detected as legacy DB.
• For issue LOAD SCRIPT screws up the path in Windows #8284 is fixed encoding of jump characters. Now windows paths can be used as paths pointing to script. Nevertheless windows path should be between quotes or single quotes

Please pay extra attention to changes in OStringParser, because this tokenizer is used on few places

@markodjurovic Can we instead of fixing of StringParser apply some local fix? You see string parse is like "treatment from all diseases" so it is risky to change it and does not have side effects.

Thanks, when is 3.0.2 going to be released in the Maven repo?

@Laa
I can implement case specific fix. I will revert changes in StringParser for now, and later we can discuss about StringParser fix (I think it is valid fix, but let double check it).

OK I will close this PR and create new one
