Improve docset installation

[xeruf]

Great tool, since I prefer the terminal, much better match for me than Zeal :)

But I think the installer could use a few improvements, firstly smart-case search (case-sensitive as soon as there are uppercase-characters):

Installable docsets (6):

        Grails, Ruby_on_Rails_3, Ruby_on_Rails_4, Ruby_on_Rails_5, Ruby_on_Rails_6, Ruby_on_Rails_7

echo Install Grails docset '[y/N]'?...^C%                                                                                    

Furthermore, I do not understand why there is a listing of all files in the docset upon installation.
If you want to show progress, maybe you want something like this: https://code.ftt.gmbh/janek/dotfiles/src/branch/main/.local/bin/scripts/rewrite

I have implemented a single-line progress indicator (using awk in POSIX fashion) in commit b2e2daf. Please try it out.
