v0.1.1

Added

• The window says "Copied to the clipboard" after it copies.
• texcopy --uninstall removes the models, the helper and the settings texcopy downloaded. --dry-run only lists them. On Linux, install.sh --remove --purge does it too.
• Human and exact output modes: --mode human|exact (or TEXCOPY_MODE) and a mode choice in the window. --raw means exact.
• TEXCOPY_CONFIG_DIR moves the window's settings folder.

Changed

• Human mode cleans more: spacing macros at the ends of a formula, braces around cells in aligned, array and similar environments, {}= after an &, and \; between plain symbols.
• The vision engine's math gets the same cleanup.
• The window is wider to fit the mode buttons.
