Minor updates to TFS Administrators Toolkit

Ive just uploaded an update to the TFS Administrators Toolkit fixing the following UI glitches:

• Unified the UI in the same style
• Update Reports now works with resizing windows
• Update Work Item Types now works with resizing windows
• Source Control Folder Size now shows sizes in a own column
• Search Large files better formating of Size column

Many thanks to Gabian for pointing those issues out to me.
