[PATCH] [RFC] Add Application property to HealthChannel

[PATCH] [RFC] Add Application property to HealthChannel

[Elvis Pfützenreuter]

This patch adds the Application property to HealthChannel, which
allows to unambiguously relate a channel to an application.

This property is useful when there are several processes interested
in accepting HealthChannels but device address is not sufficient
criteria to engage upon, or ignore, the ChannelConnected signal.
Having the application path allows to determine role and data type,
in the context of the process that has created that application.

Also, channel path skeleton is fixed in documentation, in order to
reflect atual implementation.
