Initialized branch

Created local Eclipse from Dropbox and synchronized Adam branch with
local Git repository.
Added global vars and default constructor to Client.java

Added the global variables and default constructor to Client.java. I
mostly did this just to test a code commit to the branch and confirm Git
is working.

Also, I totally had a hugely outdated version of GitGUI on my
workstation. This one's way better.
Updated client files/methods and Message.

Updated more methods in Client.java, added Display_interface.java and
Output.java and added shared/Message.java.
Added more changes to previous commit.

Finished updates to Client.java, Display_interface.java, Message.java,
and Output.java.
