xgejom.bat and ibjom.bat suppress errors

To reproduce you may temporarily replace the `xgConsole` in `xgejom.bat` with a non-existent tool. For example so:

--- a/xgejom.bat
+++ b/xgejom.bat
@@ -2,5 +2,5 @@
 setlocal
--- a/xgejom.bat
+++ b/xgejom.bat
@@ -2,5 +2,5 @@
 setlocal
 if "%IBJOM_NUMBEROFJOBS%" == "" set IBJOM_NUMBEROFJOBS=60
 set NINJAFLAGS=-j60
-xgConsole /profile="%~dp0\xgejom.xml" /command="jom -j%IBJOM_NUMBEROFJOBS% %*"
+xgNotThere /profile="%~dp0\xgejom.xml" /command="jom -j%IBJOM_NUMBEROFJOBS% %*"
 endlocal

Next in the CMD window, issue:

> xgejom.bat && echo "SUCCESS"

The result is:

Der Befehl "xgNotThere" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.
"SUCCESS"

The problem is that the "SUCCESS" is seen. It shouldn't.

I believe this is due to the "setlocal", "endlocal" in the script. As both "xgConsole" and "BuildCosole" tools are executables and the script doesn't CALL out other scripts, I don't see a need for using "setlocal/endlocal" and would advice to remove those.
