Correctly check reload_opsview parameter in types

This sets the default value of the "reload_opsview" parameter to false
for all types and fixes the check for the paramter in the respective
implementations to check for true/false instead of 1/0.
Set default values for snmp params

This is probably better done in the provider where "undef" and
true/false can be interpreted correctly into their JSON equivalents.
Always sort array parameters/properties

Do this by overriding the `insync?` method and sort both the "is" value
(coming from Opsview) and the "should" value (coming from the Puppet
manifest). This obsoletes the requirement that the user supply array
parameters pre-sorted alphabetically. Should fix issue #8.
