TODO item action group

[ForNeVeR]

Currently, IntelliJ Platform doesn't seem to allow adding any actions directly into the TODO item action list.

Instead, I somewhat hacked it by adding my action into the VersionControlGroup that's being inserted into the TODO item's context menu.

Let's introduce this capability into the platform and rely on it instead of the current hack.

See the code near this line:

Todosaurus/src/main/resources/META-INF/plugin.xml

Line 14 in 7c8e5a5

<add-to-group group-id="VersionControlsGroup" /> <!-- TODO: This is a temporary solution until the TODO tool window supports a proper action group -->

Also, look for the number of this issue in the project code base.
