Connect paths

[kylecorry31]

Choose a point on path A and a point on path B which are connected, and a new point will be created on both of the paths to reflect the shared points.

• [ ] Add a path menu option to connect two paths
• [ ] Choose the path to connect two
• [ ] Choose a point from path A
• [ ] Choose a point from path B
• [ ] Create point from path A on path B
• [ ] Create point from path B on path A

The created point show connect with either the point before or after the one selected depending on the direction.

This will allow easier navigation between paths if that is ever implemented in the future.
