v2.14.2v2.14.2

- **Exposure time finder:**
   - (Add) [ME] Option: 'Use different settings for layers with same Z positioning'
   - (Add) [ME] Option: 'Lift height' for same Z positioned layers
   - (Add) [ME] Option: 'Light-off delay' for same Z positioned layers
   - (Improvement) Auto-detect and optimize the 'multiple exposures' test to decrease the print time, by set a minimal lift to almost none
   - (Improvement) Better information on the thumbnail
   - (Fix) Importing a profile would crash the application
   - (Fix) Error with 'Pattern loaded model' fails when generating more models than build plate can afford (#239)
- **GCode:**
   - (Fix) When the last layer have no lifts and a move to top command is set on end, that value were being set incorrectly as last layer position
   - (Fix) Layer parsing from mm/s to mm/m bad convertion
- (Add) File formats: Setter `SuppressRebuildGCode` to disable or enable the gcode auto rebuild when needed, set this to false to manually write your own gcode
- (Fix) ZCode: Some test files come with layer height of 0mm on a property, in that case lookup layer height on the second property as fallback
