This plugin currently uploads the selected sticker every time, to the
HTTP File Upload service of the server (see XEP-0363), a future
optimisation would be to use XEP-0231 instead, for better caching on the
recipient side.
It relies on a helper tool to select the wanted sticker inside the pack,
a sample one is provided in tools/sticker-picker/, but it is not built
by default.
- remove “make uninstall” target which was broken a long time ago
- move very install action to the setup.py (alias “make install” to
“python setup.py install”
- add some stuff to “make clean”
- update the config.py to search the default config file using
pkg_resources (more reliable than dirname(__file__))
- install the html doc only if available
- use README.rst for the setup.py long_description
- also, update the copyright notice to 2015
