+ We discovered that Rock Custom Plugin dlls pretty much have to be in RockWeb/Bin.  Otherwise, any blocks that reference those dlls won't compile.  We even tried editing Web.config to look in other directories.
+ So, Reflection.FindTypes is updated to look in all the Dlls that RockWeb is using instead of just Dlls that start with the word "Rock".  It also narrows it down to Dlls that reference Rock.dll.  It is just as fast as before.  Less than 35 ms.
