#45 missing shebang line

[Wart]

The checker and compiler are missing the #! line to
invoke the proper interpreter in the startup.tcl scripts.

Additionally, the checker is missing a 'package require
procomp' needed to load the procomp package. And
procomp.tcl is missing a 'package require cmdline'
needed for its command line processing.

The attached patches fix these problems.
