A very long time ago CL 2411381 introduced a change to make the default Base Indent Level of all Graph Action Menus "1", basically meaning that both "0" and "1" indent levels would be placed at the root of the menu. Presumably they've needed it, because in BPs, categories on the left side are custom headers, and they didn't want the children (functions, variables, etc) to have an extra indent.
However, they've made this change globally, basically breaking Graph Action Menus that didn't have category customization and needed the first level to be indented under the root level.
Some systems have overcome this by defining a custom expander with a Base Indent Level of 0 - getting back the original, expected behavior. That was however just hiding the underlying issue.
This change reverts back the Base Indent Level to 0, and sets it to 1 instead only for those menus, which have a customized category header. This should fix all graph menus where the second category level was not indented (i.e. BT Action Menu and Decorator Context Menu).

"Crash occurs when scrolling down through files in Review Changelist window upon loading of asset"
- certain widget blueprints were crashing the review tool because we were working around the inability to diff against nullptr by constructing temprorary empty objects. This approach circumvents that problem entirely
#jira UE-173231
"Changelist Review tool allows diffing against previous revision for Deletion changes"
- while this jira suggests that the ability to diff deletion changes is a bug, it was actually an intended feature. The real bug was that it would crash or fail to work in many cases. This has been fixed by either asset diffing against nullptr or text diffing against an empty file (depending on circumstance)
#jira UE-174610
"Reviewing Changelist with Deletion Changes results in LogLinker warnings & LoadErrors"
- deletion changes were trying to load the new revision of files but obviously it doesn't exist because it's a deletion. Fixed by only loading the previous revision
note: since the review tool is going to be "Production Ready" in 5.2, these changes are neccesary for stability
