TopNav & SideNav changes | Logo + menu trigger

[SamusElderg]

Now that we have moved elements from the topNav and have room on all screen sizes (potentially) for the full horizontal logo, lets make the next few changes. This will also solve the sometimes-bad-UX aspect of locking the sidebar on medium desktop screens (you will be able to click the lock button even when you hover over the sidenav)

Currently:

Proposed (Rough obviously):

• On hover of hamburger icon when sidebar is not locked, show a locked padlock
• On hover of menu (not hover directly on hamburger icon) show unlocked padlock
• Not hovering over either && sidebar not already locked: show no padlock
• Not hovering over either && sidebar already locked && screen not large enough to always be locked: show locked padlock

partial with 9b3ecd1
still need to consider adding the 'lock' icon in some cases

I think we can close this now its basically already done indirectly except the lock icon stuff but i just created a branch and did the work and think the UI/UX is no better or worse, will just leave it as is for now
