You uninstall a package in the "Package" > "Install/Uninstall packages" 
dialog. Select the package to be removed in the left list, click 
"Uninstall selection" and then "Save and Rebuild IDE".

This will remove bglcontrols which is a runtime/designtime package, but 
it will not remove bgrabitmappack - it is a runtime package and thus is 
not compiled into the IDE. This cannot crash the compilation of the IDE. 
If you also want to get rid of it, go to "Package" > "Package Links", 
find it in the list, check it and click "Delete selected". This removes 
the path to the package from an internal list so that the IDE no longer 
knows where the package is (the files are still there, though - but you 
can delete them manually in the OS).
