Comment:

 I've discovered that `GHCiState` already stores the `progname` but does
 not use it when generating a source location for parsing/evaluating
 statements.  Instead `<interactive>` is hard-coded in `hscParseThing`.  I
 have updated the code to use `progname` in the source location so that
 scripts can set `progname` to the file name being loaded.

 Also, I have updated the specification of `:script [n] <filename>` in that
 the optional integer is the line number after which to stop, nothing
 fancier.
