+Bugs:
+
+- Update the "Got client connection from" message to actually display a correct message.
++ Send all clients a message when someone joins the server.
++ Clean up messages!
++ Put all the "magic" strings into a central class. (HELO, QUIT, etc)
++ Take care of the magic number. (Same class as above.)
++ put a static gettype(string) function into abstractmessage
++ There is no way to get chat messages out of messagelist. Make one.
++ If there is a colon as the last character in the message, my parse method doesn't work (chat, say) Same for colon being the first character...
++ The content pane in chat panel doesn't scroll...
++ HTML don't work. Do a styled document, like it says in the tutorial!
++ Look into the problem of resizing the drawing canvas.
++ Look into the problem of giving the color indicator some size.
+Look into the problem of loading resources.
++ When right-clicking, the tool doesn't exactly set off... Instead, it just resets the first position to -1, -1, and remains active...
++ Make it so that the textmessage stores the font parameters as actual bits of information, and only assembles the entire font when getFont is called. Otherwise, server gets fucked up.
++ Make it so updateFont of font selection panel makes the graphics panel rerender.
++ Test out this focus deal. Sometimes, the key presses may not register.
++ Implement different cases for key presses in key tool - caret, arrows, backspace, esc.
++ Pretty up text tool rendering - put a box around the text maybe?
++ Test out the finalize button it may get fucked up sometimes.
++ Make it so when one hits enter while entering text, not only is the message finalized, but also the font panel disables the finalize button.
++ Implement processXMLElement and propertiesToXML for graphics messages and the chat message.
++ There seems to be a bug in the isConnected method of Client.
