Codex community layout

[scorreard]

This update will create the final files necessary to display the community table in the new Codex layout.

You can see what it looks like here :

Changes to the code :

• Created the html and md files for the microgalaxy community for tools, tuto and workflows (These files are used as template for other communities)
• Updated the code (get_community bash scripts) to automatically create these files for other communities who have a Codex folder
• Updated the navigator to include the Community specific table in the navigator bar

When a community is ready to display their community specific tables, they will have to manually update the topnav file (I will include this step in the codex tutorial).

Issue :
I think the current theme only support ONE level of dropdowns, not nested dropdowns. It may need to be adressed once many communities join the codex.
