Menu and team visual fixes

Hi,

I have created some visual improvements to the menu and team section.
(I can revert some parts from it, like team section if you are not happy with solution :) )

It fixes this bugs:

Menu is overlapping the logo

Menu is again overlapping logo and last submenu is going out of window.

This is happening currently only in repository, not live site, the team members will not fit the row because they are inline blocks and there is white space in between them. I have also noticed that they have some margin from right, so every row have different spacing form left/right
