Switch to different clipboard library (AttributeError: When using gi.repository...)

[dynobo]

pyperclipsomehow has some long outstanding issues with GTK3, e.g. throwing:

[...]
File "/home/dynobo/.local/lib/python3.8/site-packages/pyperclip/__init__.py", line 158, in copy_gtk
    cb = gtk.Clipboard()
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 72, in __getattr__
    raise AttributeError(_static_binding_error)
AttributeError: When using gi.repository you must not import static modules like "gobject". Please change all occurrences of "import gobject" to "from gi.repository import GObject". See: https://bugzilla.gnome.org/show_bug.cgi?id=709183

Let's switch to a more up-to-date library, like e.g.:

• pyclip
• crossclip

Switched to pyclip with v0.1.11.
