Editing component being compiled when compilation failed.

And one more comment to be as clear as possible :)

My file contains several independent things:
1. package-file, of-system: are not very interesting, lets ignore them.

2. fake restart to allow calling editor from the debugger. The most
interesting.

3. tools to enable finding a form definition by system name via M-. in SLIME
or Lispworks IDE. Rather useful.
