Receive combined text messages on Android

[bear101]

@poretsky In TeamTalk v5.9 I've added 'bMore' member variable to TextMessage-class. When 'bMore' is set then the current message type (nMsgType) is part of a combined message. The combined TextMessage ends when 'bMore' is cleared (false).

Can you find a way for TextMessageAdapter to support this type of messages? Basically TextMessageAdapter should not update until all TextMessages with 'bMore' has been received.

Here's how TextMessages are split:

Here's how TextMessages are combined:
https://github.com/BearWare/TeamTalk5/blob/android-recv-longmsg/Client/TeamTalkAndroid/src/main/java/dk/bearware/data/MyTextMessage.java#L99

Here's an example of sending a TextMessage:

@beqabeqa473 Maybe you could also have a look at this

This PR so far only does the merge part of TextMessage. TextMessageAdapter should not show the message until bMore=false.

Maybe it's enough to change TextMessageActivity.onCmdUserTextMessage() to not update if bMore=true.
