Title: Raise an error during capture if CutyCapt is not installed

If CutyCapt is not installed and I attempt to capture a webpage, the current error is cryptic:

sh: --: invalid option
Usage: sh [GNU long option] [option] ...
sh [GNU long option] [option] script-file ...
GNU long options:
--debug
--debugger
--dump-po-strings
--dump-strings
--help
--init-file
--login
--noediting
--noprofile
--norc
--posix
--protected
--rcfile
--restricted
--verbose
--version
--wordexp
Shell options:
-irsD or -c command or -O shopt_option (invocation only)
-abefhkmnptuvxBCHP or -o option

I added a friendly error message instead:

RuntimeError: Cutycapt is not installed.
