This change makes errors messages show up in the replies, too.
Before (notice how the third command does not generate output):
$ awesome-client 'return 42' ; awesome-client 'sdfsdf' ; awesome-client 'error("foo")'
double 42
string "[string "sdfsdf"]:1: syntax error near <eof>"
After:
$ awesome-client 'return 42' ; awesome-client 'sdfsdf' ; awesome-client 'error("foo")'
double 42
string "[string "sdfsdf"]:1: syntax error near <eof>"
string "Error during execution: [string "error("foo")"]:1: foo"

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.
