VIX-444 - Unable to set change interval to less than 100ms in Alternating Effect

VIX-444 - Unable to set change interval to less than 100ms in Alternating Effect
Modified AlternatingEffectEditorControl.cs - trackBarInterval.Minimum property to have a value of 1 instead of 100

Change was made using the Visual Studio Editor, which causes the diff to show a large number of lines of code changed.  In reality the only change was to trackBarInterval.Minimum which was set to 1 instead of 100.

This change also requires one other change, which was made by Jeff Uchitjil on EditorRevamp branch commit 8bd355512a77866ec3afa42f8e1619e6a8243ecf which is waiting to be pulled also.
