Overrode accept slot in UdpSetupDialog

Moved signal/slot connections back to the UI file. Overrode accept() so
it saves anything set in the dialog by the user before hiding the
dialog.
Modified SerialSetupDialog to use UI signal/slots

Moved signal/slot connections to the UI file. Overrode the accept()
method just like with UdpSetupDialog. Using the widget slots for things
like comboBox index changed instead of custom named slots.
Modified UdpSetupDialog slot

Got rid of the custom named signal. Using the pushButtonDefault's own on
clicked slot now.
Fixed map layout

Got map to expand correctly by (1) making it the first tab in the tab
view (for some reason Qt knows the base size right away when you do
this), (2) setting a base size on the QWebView widget, and (3) setting
the layout strech to 1,0 for the horizontal layout which holds the map.
Added comm classes

These classes will be responsible for receiving and transmitting
messages. These all need to be implemented, this commit is just adding
the class files to the project!
