[rygel/wip/basic-management: 57/68] core: Handle default parameter values in BasicManagement NSLookup

[Jussi Kukkonen <jussik src gnome org>]

commit d7c830aad1873e5e0ff7b7247f260f26b4ee6d10

    core: Handle default parameter values in BasicManagement NSLookup
    
    Add property setters for repetition and timeout, so the default values
    can be used for value '0'. repetitions still uses base class 'iterations'
    variable internally.
    
    Rename variables in BasicaManagement to be clearer.
