"Text" should be one of the possible media in a call. [RAUR]

[gunnarhm]

In Introduction, in the middle, in this sentence:
"This allows instantaneous applications for video and audio calls, text chat, file exchange, screen sharing and gaming, all without the need for browser plug-ins."
", text" is proposed to be added after "video" as media in the call, by that enabling both real-time text and message-wise text-chat.
Modifies text:
"This allows instantaneous applications for video, text and audio calls, text chat, file exchange, screen sharing and gaming, all without the need for browser plug-ins."
