During discussion in #702 we came to a decision that we need a new separate section for libraries.
This PR adds the mentioned section and it also hides the sections without lessons from the sidebar.
cc @doomspork @brain-geek @ybur-yug @Koziolek and everyone else.
Once this will be merged, #702 and #431 will require corresponding updates (location, order and category). Then I'll also create an issue for translations.
Add the new section for libraries
Let's merge it with at least one lesson in this category. e.g. after #702 gets merged.
LGTM, I'm just with @brain-geek on waiting til we get atleast one item in here (i.e Poolboy once its done, which it seems to be quite close)
Looks nice, let't merge it with first lesson plus add some info about library vs specific, because sometimes is hard to say what is what.
Agree with the others, let's wait to merge until we get the first lesson in.
Looks like we need to update the configuration for the new ruby version on Heroku to get this one synced properly with master now
Actually the conflict was caused by another set of changes. Anyway, I merged latest master into this branch and resolved it, so the latter one is mergeable again.
