Added new property max-resumption-timeout to @StreamManagementIOProcessor@.

Now it is possible to set default resumption timeout used by server if client will not pass how long server should wait for reconnection

c2s/processors/urn\:xmpp\:sm\:3/resumption-timeout[I]=90

and to set maximal timeout which will be allowed by server

c2s/processors/urn\:xmpp\:sm\:3/max-resumption-timeout[I]=900

+Note:+ Before this change maximal resumption timeout value was equal to value of resumption-timeout property and by default was equal to 60 seconds and now is 900 seconds is default value for maximal timeout.

Looks good to me, however, I think that for our mobile client needs we will need the "max" timeout to be set to at least 3,600 seconds.
