Added Arguments parsing to support grid renaming and disabling of auto-hide feature.

Arguments (Command-Line only);
Reset -- Resets the names of all blocks on the grid to default. Use with caution.
DoHiding = bool -- sets an internal flag to disable or enable autohiding. default: true.
GridName = String -- sets the name of the grid running the program.

Added auto-hiding of selected niusance blocks and all grouped blocks

Fixed issue where renaming a grid caused whitespace to be continuously inserted after header.

Fixed a slight logic error that I had missed which may have caused lag if script was run frequently.
