Improve VisualScript UX

* Prototype faster function call ux.
* Work on general search ux.
* Able to create nodes from search.
* Show class for variables but not methods.
* Get actions search working.
* Descriptions now show for both methods and properties.
* Enable zooming on mouse wheel up and down.
* Make the drag trigger on right mouse button.
* Search now shows for action visual script nodes.
* Able to search visual node names.
* Search works better.
* Change zooming scale to hide artifacts better.
* Remove zoom changes
* Select from base should check properties too like the other functions.
* Seq_connect flag is needed to set sequence lines correctly.
* Remove comment
* Code cleanup with function names and arguments.
* Use brief description for search descriptions.
* Clean and fix bug with input nodes connecting with sequence lines.
* Add a warning and fix some edge conditions with sequence into data lines and vice versa.
* Don't search functions when pulling from a sequence node.
* Don't show actions when pulling from a data line.
* Set set and get properties.
* Convert visual script operators to the correct type
* Create a function preset finds only functions.
* Singletons can now find functions.
* Add shift-a for generic search.
* Add brief descriptions for Visual Script nodes.
* Search boxes can now filter names.
* Add bigger hit zones to node connect.
* For the drop zones, make all the rect2 areas the same size.
* Function names in visual script node should be lower case so that search works better.
* Use the convention of capitalize() for set, set, visual script nodes and methods.
* Make search more general. Ignore "_" and make case-insensitive. Also made the search window smaller and remove extra info from search
* Make type_cast use the connecting node's type and remove use of found variable.
* Fix case where you call an instance's call function where it becomes an invalid call.
* Make get_visual_node_names use a set of filters, move action creations and fix bug with sequence node connections.
* Make the window bigger.
* Make connect_data and connect_seq more robust.
* Add icons to search items.
* Add vs constructors in shift-a menu.
* Operators, builtins and constructors show type name. Fix several problems with port connections.
* In shift-a mode search everything.
* Code cleanup
* Work on autocompleting the type.
  * Use type guess in action creation.
  * Check if type hint string exists in object variables when generating the visual script search.
  * Add the hint to SceneTree.
  * Add original type detection.
  * Make type casting great again. This puts the type casted base type as the data output type string hint.
  * Pass the type in a VisualScriptFunctionCall too.
  * Set the base type correctly in VisualScriptFunctionGet and VisualScriptFunctionSet using hint string.
  * Make sure the instance is passed in VisualScriptPropertySet.
  * Restore search on the node's type.
* Remove dependencies from graph_edit.
* Remove dependencies from property_selector and name the class visual_script_property_selector.
* Extract hot zones into a function.
* Move hot_zones constants into default theme.
* Bigger capture zones.
* Clean messy port_grab_distance variables.
* Remove RMB functionality.
* Remove memory leak on showing visual script descriptions.
* Read the port_grab_distance constants on enter tree and theme changed.
