IDEA-115794 Settings vs Preferences?
gradle: do not skip configuration of custom buildscript classpath if distribution type was not configured
[git] IDEA-68866 IDEA-134424 support reword & fixup (including initial)

If commit message starts with "fixup!", then interactive rebase
editor will start the line for this commit with "fixup" action,
not "pick" => assertion is invalid.
Instead supply the GitRebaseEntry with the initial action value.

Add "fixup" & "reword" to the Action enum, no other special
support is needed (IDEA-68866).

Cleanup (update installation methods got more distinctive names)
