Changed a few in pop up of mouse plugin to just show ZOOM and SELECT.
Changed a few in menu of visualization algorithms to not show unneeded
things (like ZoomedLayoutForModules*).
Fixed the zooming bug, when you zoom in a module.
Fixed bugs of Big Icons (actually removed it from menu).
Fixed topological travel since it produced error in repaint of graph
when a "Highlight Impact" button was pressed for an event to take place.
Removed many things from the popup menu of the mouse since they were
unneeded.
Removed some unneeded functions (maybe there are many more).
Fixed somehow the visualization of a zoomed tab.
