Subject: Implement zsh shell completions.
X-Git-Url: http://biod.pnpi.spb.ru/gitweb/?p=alexxy%2Fgromacs.git;a=commitdiff_plain;h=6990a0a5035c28011ee8a667df19d4ff0fc3b3d1

Implement zsh shell completions.

zsh completions when gmx prefix was used were not implemented. Use zsh builtin
bashcompinit to use the bash completions. Remove 'shopt -s extglob'
from gmx-completion.bash and place it in GMXRC.bash, since it is incompatible
with zsh. gmx-completion.bash and gmx-completion-gmx.bash can now be used for
completions in both bash and zsh.
