More complete eagleeye implementation, share with you

It mainly implements the following: 1. load mxd file synchronization; onmapreplaced event 2. load layer file synchronization; onitemadded event 3. check the state of the layers in TOC and synchronize the visible state of the layers in eagleeye; contentschanged event 4. right-click the eagleeye view and select the display area in the main view. 5. in the eagleeye view, left-click to center the rectangle. 6. right-click the TOC menu and choose delete layer;
