Release 1.4.1

Change-Id: I44cb7b5b199192399e1e5edf180151bc20cb7fef
Send timezone update message on initial login

Piggybacks on the AppRTCClient VideoParameterGetter async task. Right
after sending the VIDEO_PARAMS request, it sends another request with
type TIMEZONE containing the local default timezone ID string.

Requires the following commits in the protocol and svmpd:
protocol-def >= 7a56c1175b33236d7ba21fc27c3044e1e49e7aa4
svmp >= b64b724fe65620c19ea01cd82b5886e1c5b66efe

Change-Id: I119fdd0d4bdb0c99df05f60bf54b931dff898583
Added support for single app mode

Added capability for client to keep a list of apps that are
available on the VM, maintain separate "favorites" list, add
direct home screen shortcuts, and launch directly into specific
apps on connections.
Abstracted out AppRTCActivity functions and created two child
activities, AppRTCInfoActivity and AppRTCVideoActivity, to allow
for multiple points of entry when connecting to the VM.
