[ER] UI needs right click menu everywhere

Standard windows design and expectation by windows users is to have a right click menu for everything. This app deviates from that standard and as such, is uncomfortable for users.

For example, on the firewall tab, should be able to right click and see On/Off and Advanced. (On/Off depending on current state). Advanced should take me to a full profile editor where I can restrict flow inbound/outbound/source/target/protocol/label of the application/etc.

Please progress towards standard usability features for windows, such as having right click menus.

We will try to increase usability in the future. I just checked Firefox and confirmed it does this with tabs and we can do the same.

We tried adding right clicking on the graph but found it confusing so we changed it where a line appears on mouse over and it works with a left click.
