replace the SQLite download with SQLmanager about library-sql-deprecated

#62 and datacarpentry/sql-ecology-lesson#199 seem extremely related to this.

Once a new solution to those has been found, revisiting the core concept in this issue sounds like it'd be useful. 😄

Repeat from #38: We cannot assume that librarians a) have Firefox b) know Firefox c) have the admin rights to install Firefox

Okay. I realise - thanks @ostephens for the prompt! - that c) would be the same for SQLite and Firefox. I'm just worried about Firefox dependency hell. Where is the Data Carpentry discussion that justifies the use of a Firefox plugin. I don't want to reinvent the wheel.

Data Carpentry workshops often don't teach shell and don't expect learners to know it. I think this is why they chose to use Firefox plugin in their workshops.
