kapow server powfile.pow should exec powfile.pow if possible

[panchoh]

As a Kapow! user, I would like to control the scripting I use to configure the kapow server.

Right now, the powfile.pow is always treated as a bash script.

But, if I wanted to use a different method to call kapow route..., say from a dash script, Perl script, Python script, or bash script but selected via #!/usr/bin/env mechanism, I couldn't do it cleanly as it is now.

I propose to implement a teeny tiny bit of logic to examine the executable bit of the powfile.pow, and try to exec it instead of passing it to bash.

kapow/internal/cmd/server.go

Line 55 in f4b9a96

kapowCMD := exec.Command("bash", powfile)
