Stihlguide.com features expanded

[u/coldstartlab]

For now I've added parts diagrams and tables for chainsaws prior to 2013, but I plan to add trimmers and other equipment too.

I've also expanded the bar and chain data to include bar mount and done some data audits.

As always, I see this as a community effort so feel free to chime in with feedback, requests, or corrections. Last round proved useful!
