During development the git branch will be added to the version name. In releases, as there is no git repository included, the __version__ will not be modified.
* make last modification time check on status asynchronous using a dedicated thread + use a ThreadPool to run tasks in parallel
* avoid UI freeze when checking for status updates + increase performances
Introduce a new TextFileViewer component with auto-reload feature based on a ListView instead of a TextArea for performance reasons. Uses the text content split on line breaks as ListView's model.
Features:
* auto-scroll to bottom
* display line numbers
* customizable line delegates (e.g.: display a real progress bar)
* color lines according to log level
* range 'blockSize' is now the complete block size (equal for all iterations)
* command lines nodes can use this complete block size to compute the iteration number on software side; delegate range cropping for last iteration to software.
* 'effectiveBlockSize' is still accessible through 'rangeEffectiveBlockSize' parameter

Usage of DelegateModel for model filtering has not proven to be the most stable solution, and might be responsible for random crashes happening during engine's garbage collection. Implement Loader-based alternative:
* first delegate is a Loader which creates the AttributeItemDelegate if necessary
* compensate spacing using negative height when element is hidden
If an outside 3D media file is the first thing ever loaded, 'model.attribute' will be initialized to 'null' and will prevent an actual Attribute to be associated to this role. This breaks media loading from within Meshroom.
* add 'matchDescription' method on desc.Attribute.
* desc.ListAttribute/desc.GroupAttribute: 'matchDescription' ensure that value perfectly match element/group description. Enable recursive checking for child attributes.
* nodeFactory: detect DescriptionConflicts in pre-process pass by checking that serialized node's attributes perfectly match their descriptions
* CompatibilityNode.attributeDescFromNameAttribute: consider link expressions as valid values
* test_compatibility: more complete description conflicts unit testing
