--User changes
-Add a new dialog for editing QSS stylesheets. Allow for saving, reloading and setting styles as default. --Include a dark style with the installation called dark.qss. --Also add support for themes such as Fusion. --Resize some controls to better fit with the new style. -Add an option to specify the number of random embers generated on startup. 1 is the minimum and the default. --Bug fixes -Properly enable/disable thread priority label in final render dialog in response to enable/disable of the OpenCL checkbox. -Remove all inline stylesheets. -Show xaos spinners with 6 decimal places. --Code changes -Remove redundant comparisons to nullptr, use ! instead; -Give some controls valid names instead of the auto generated ones. -DoubleSpinBoxTableItemDelegate.h: Add virtual keyword to overridden functions.
