Xendomains was not correctly suspending domains when a STOP was issued.

The regex was not selecting the { when parsing JSON output of xl list -l.
It was also not selecting (domain when parsing xl list -l when SXP selected.

Pefixed { with 4 spaces, and removed an extra ( before domain in the regex
string

Added quotes around the grep strings so the spaces inserted into the string
didn't not break the grepping.

This has now been tested against 4.3RC5
