FBIde 0.5.0.rc-6

Changes since 0.5.0.rc-5.

• Fixed status bar getting stuck on a stale compile message (#106).
• Fixed crash when quitting from the macOS dock menu (#107).
• Fixed minimap not using the theme’s change-marker colours until the Settings dialogue was opened.
• Fixed BOM-marked files with invalid bytes being reinterpreted as Latin-1 and losing their BOM on save.
• Fixed on-type case conversion occasionally altering a keyword just past a pasted block.
• Optimised single-line lexing (e.g. auto-indent on Enter) to not allocate whole-document capacity in large files.
• Fixed compiler log mangling output that contains square-bracket markup (e.g. [b]).
• Fixed potential crash when quitting during an in-flight update check.
• Fixed Find/Replace dialogues stacking up when reopened; the open one is now raised instead.
• Fixed crash when a second instance forwards a file during the splash screen.
• Fixed Settings partially applying (and restarting for a language change) when another tab had an invalid value.
• Fixed crash when re-selecting a newly saved theme in Settings.
• Fixed potential crash on multi-line edits.
• Fixed cleanup of async tasks when FBIde quits.
• Optimised multi-line edits to avoid re-lexing the document from the beginning.
