* **(Fix) PhotonWorkshop files: (#149)**
* CurrencySymbol to show the correct symbol and don't convert unknown values to prevent hacking
* Set PerLayerOverride to 1 only if any layer contains modified parameters that are not shared with the globals
* **(Fix) Clipboard:**
* Initing the clipboard for the first time was calling Undo and reseting parameters from layers with base settings
* Undo and redo make layer parameters to reset and recalculate position z, making invalid files when using with advanced tools
* (Fix) Tool - Edit print parameters: When editing per a layer range and reopen the tool it will show the previous set values
