v2.7.2v2.7.2

* **Core:**
   * Fix some improper locks for progress counter and change to Interlocked instead
   * Fix a bug when chaging layer count by remove or add layers it will malform the file after save and crash the program with some tools and/or clipboard
   * Fix when a operation fails by other reason different from cancelation it was not restoring the backup
   * When manually delete/fix issues it will also backup the layers
* **LayerManager:**
   * LayerManager is now readonly and no longer used to transpose layers, each FileFormat have now a unique `LayerManager` instance which is set on the generic constructor
   * Implemented `List<Layer>` methods to easy modify the layers array
   * Changing the `Layers` instance will now recompute some properties, call the properties rebuild and forced sanitize of the structure
   * Better reallocation methods
* **Clipboard Manager:**
   * Add the hability to do full backups, they will be marked with an asterisk (*) at clipboard items list
   * When a partial backup is made and it backups all the layers it will be converted to full backup
   * Clipboard can now restore a snapshot directly with `RestoreSnapshot`
   * Prevent restore the initial backup upon file load and when clearing the clipboard
   * Clip's that change the layer count will perform a full backup and also do a fail-safe backup behind if previous clip is not a full backup
* **Pixel dimming:**
   * Allow to load an image file as a pattern (Do not use very large files or it will take much time to dump the data into the textbox)
   * Empty lines on patterns will be discarded and not trigger validation error
