Commit retro-220 emulator version 0.07:

Browse Source 
1. Implement centralized pop-up window opening mechanism to enforce a delay between pop-up opens. This is to satisfy new restrictions on multiple pop-ups imposed by the Apple Safari 11.0 browser.
2. Correct Reload-Lockout behavior and format band 6 initialization in B220CardatronInput.
3. Correct translation of sign digits and skip-to-channel behavior in B220CardatronOutput.
4. Strip sign digit from search/scan argument word when storing into B220MagTapeControl T register.
5. Remove option for 1000-word system memory size and correct handling of memory size list selection in B220SystemConfig.
6. Change reel-to-reel magnetic tape name from DataReader to TSU in B220SystemConfig.
