Added a $self->{'cookie'} variable.
 Added a proxy object in testcases.xml.
  It can be used to override config.xml proxy definition ("no_proxy" will disable proxy, setting another proxy will override, authentification should be handled).
  It can either be used to set a specific proxy in some case if not defined in config.xml (in this case no_proxy is useless).
 Added returnmessage set on verifs even if break_on_errors is off (short messages), last failed varif will be used.
 Added a new hash to store global outputmessage (first key is the testcasefile number in read order, then testcases in numeric order).
  If an errormessage is set in testcase it will be used, otherwise last returnmessage will be used.
