Add snap and lock angle modifiers for handle dragging to the Path tool (#2160)

* added snap and lock angle to path tool

* fixed breakage of `tab` and `space` functionality
- Previous implementation broke functionality of using Tab to swap the being-dragged handle to its opposing handle, Now fixed.
- Previous implementation broke functionality of using space to drag the manipulator group (anchor + handles) while dragging a handle, Now fixed.

* fixed the angle snapping and locking when used together
Now, if `shift` is used to snap to a 15° increment, then `ctrl` is used to preserve the angle, releasing the `shift` key will still preserve the angle.

* Fix snapping angle logic

* Improve transforms

* added functionality for `alt` key
Now, temporarily converts selected handles to colinear if they are not already colinear.

* Revert "added functionality for `alt` key"

This reverts commit f12ba6fdbf261291ced0e042a2dfe12cddd2f9e8.

* Code review
