Fix automatic buffer reopen, modifying ctrl-left/right semantics inline with vscode/sublime, modifying load word semantics

 - We need regex for: [FormatCode matching, IsCode matching,
 - Variable documentation
 - Project configuration (the semantics: pass through command line (don't like simply open in dir) or use command to open?)
-- String16 string         <<<@= GetString(buffer, pos_range_of_line); - here deleted space + 'string', seems like same behavior as lite but different from Sublie/VSCode
 - IndentKind has issues with stuff still like cleaning whitespace etc.
+- Remedybg commands integrated! (like clicking f5 and opening up the window)
 
 Use session 4
 - ListVariables instead of GenerateConfig, auto saving of variables
