Modernize Textual

Notable changes:

Notable changes (incomplete):
• Changed all projects minimum target to OS X 10.12
• All xib files and custom view source files have been modified to use auto layout, NSGridView, NSStackView, and other modern features wherever possible. Hacks such as specifying heights, offsets, etc. for multiple appearances spanning multiple operating systems are no longer needed because auto layout and related systems are solid back to our target.
• In response to system-wide changes made in macOS Big Sur the width of the Preferences window has been expanded to a minimum 670.
• Deprecated Cocoa APIs have been replaced with their modern equivalents.
• The System Profiler plugin has been modified to simplify the process of requesting model information from Apple. The previous class (TPISystemProfilerModelIDRequestController), now named TPISystemProfilerModelRequest, at one time used XML parser to retrieve value of a single element. This made maintainability difficult. It now uses a simple regular expression.
• Optional extensions (Blowfish Encryption, Caffeine, and Wiki Style Link Parser) had their versions bumped and repackaged into installer. Their xib files were modified to accommodate the new width of Preferences.
• The Blowfish Encryption extension has been updated to libressl 3.1.4.
• All code related to the never completed "Buddy List" dialog has been stripped. There is no interest in continuing development of it.
