Version output improvements:
* Added more consistent indentation. (Matches SM's version output formatting now).
* Added missing newline after compile date.
* Added Build ID.
* Removed duplicated compile time.
* Re-ordered lines to have version numbers before compile/build information. (Again, to be formatted similar to SM's and more readable).
Refactored to have version and credits output logic not duplicated between server command and client command.
In core, moved engine names to near top of file instead of having huge list right in the middle of command output.
