Add: Param to specify filename for AddDelayedCode

You are now able to specify a file-name for addDelayedCode. This can
simplify debugging internal error for files added using AddDelayedCode.

Note: `Simba/Units/misc/LPDump.pas` has to be updated for simba to
compile with this change.
addDelayedCode set default name to 'addDelayedCode'
addDelatedCode (header) set default name to 'addDelayedCode'
