Here's a pretty large patch that implements a major refactoring of the runtime code. Specifically:
- Move the bulk of the core code from main() into a new Runtime class. - Break up the mass of code that was main() into a number of relatively simple functions. - Make the Configuration dialog synchronous so the Log dialog can be properly viewed. - Enable/disable menu options at the right time. - Remove support for Qt < 5.0. - Remove the application name constant and hardcode the name to simplify the code. - Improve log messages. - Replace the sdbm hashing with Qt's MD5 hashing.
Please review & test, but do not commit before next week's release.
