Add scroll bar

[hjs0410hc]

as this client keeps all the messages transferred in the server, when i need to see older message, i should scroll the screen up all the time. there is no scroll bar, so i just had to swipe and swipe.. so adding scroll bar would be a nice idea.

• if possible, like HexChat(windows irc client), the line which indicates the last message i saw would be nice too.

another suggestion.. new message indicator. currently there's no function like that, this cause us to miss the lastest messages, as the screen doesn't change if the screen is scrolled up.. so if there's new message, making one button that pulls the screen down emerge would be perfect..

thank you for reading, sorry for some wrong english.

As for scrollbar, it's likely not going to happen as I have no idea how much data do I actually have on the disk.
