Rename apppot-start to apppot-sh?

[GoogleCodeExporter]

I came to think that `apppot-start` is a bit of misnomer: the UNIX convention 
for commands that start another command in some environment is to call them 
"*sh": for example, `ssh` or `qrsh`.  In addition, the difference in purpose 
between `apppot-start` and `apppot-init` is not evident from the name.

So, I would suggest renaming `apppot-start` to `apppot-sh`.

A counter-argument could be that we already have delivered presentations with 
the name `apppot-start` and all our users (the few of them) are already 
accustomed to `apppot-start`.

Thoughts?
