Abbreviations of command line options are not supported anymore.

Using abbreviations for CLI options was never considered to be
a feature of pylint, this fact being only a side effect of using optparse.
As this was the case, using --load-plugin or other abbreviation
for --load-plugins never actually worked, while it also didn't raise
an error. Closes issue #424.
