changed the node action panel frontend functionality into an overlay that has clickable icons that perform the necessary functions
added in the node interaction icons for deletion and editing of nodes as well as the creation of nodes and connections. the icons were provided by travis
added dialog functionality from jquery-ui for the choice of object type to be added and editing a node
added in all the images, css, and js required by the jquery-ui version now being used
added css to handle all the new dialogs, icons, overlays, etc. as per travis's design. closeenough.jpg...sorta.
added html to do all this as well ^
fixed an issue where the connection squares weren't re-styled/reset after de-selecting the connection
updated the updatenode function to use the newer system node text retrieval process
added (?) a keyup for the system name input field to disable the submit button when the field is cleared. i could swear this was in already..maybe i deleted it. take me to jail.
changed the document onclick to just catch clicks in the svg/body area for simplicity's sake
