#8 Make search case insensitive

[Skippy le Grand Gourou]

Currently the search and file-search are case sensitive. This can be quite painful when you don't know the actual name of a package, which may be quite different from what you can expect. For instance I spent ages trying to figure out how to install mplayer, which is actually in the repositories, just because it is labelled MPlayer. Apparently KDE is labelled kde, etc. Hence finding a package is not always straightforward.

It would be great if slackpkg was case insensitive, at least optionally and/or for the search/file-search options — and at the very least mention in the manpage that it is case sensitive.
