Added support for other names than vboxmanage.

Currently the completion script will be available for commands:
VBoxManage and vboxmanage. With this commit, renaming/linking this
script with another name will also make that name to be included to
completion.

For example, with alias:

    $ alias vb="VBoxManage"

linkig completion script into new name an source it:

    $ cd /path/of/completion/script/
    $ ln -s VBoxManage vb
    # source vb

will start to complete vb command.

VBoxManage
