PCB Server is now started automatically. PCB documents are now opened automatically. Via tenting checker now reports total number of vias found, closes #167. Added script that can swap two PCB components, closes #166. Fixed 'Checking bottom dimension layer...Enum = 12Enum=12Enum=12...' bug, closes #165. Fixed the layout of the Pre-release Checks window (size needs adjusting), closes #156. Fixed the error 'ERROR: Could not retrieve 'C:\MCU.SchDoc'. Please compile project. ERROR: No sheet found. ERROR: No sheet found.' if any schematic sheet is not open when pre-release checks are run, closes #155.
