Cleanup: Put includes in alphabetical order

Joining GP objects also merges + fixes animation data for the merged datablocks

Cleanup: Make it clearer which datablock/object we're dealing with

* gpd_act -> gpd_dst ("_act" could also mean "active one we're looking at now)
* gpd -> gpd_src (we sometimes refer to "gpd" as the active one we're working on)

Fix parameter list after merge

Merge branch 'blender2.8' into greasepencil-object

Cleanup: comments and reorganize

Apply all modifiers first

The previous commit was the Context missing as parameter and this was the reason of the errors
