- better handling of drawer state using chat state manager
- removes various float and topic occurrences to use drawer
- ensures user can chat before doing a lot of chat setup
- fixes a bug which was creating presence errors in tests
- removes dead code
- Note this is also tweaking the UI a little bit as we are now using links/buttons in the header as needed
- It disables the find ideal channel in drawer mode, if loading `/chat` in drawer mode it will either reopen at the last position or just stay on index
Clicking a link of the sidebar will now open the drawer and load the correct channel.
This solution should correctly solve these cases:
closing drawer, clicking sidebar channel, should open the drawer on correct channel
visiting /chat then visiting / and clicking sidebar channel, should open full page chat on correct channel
This commits makes sure we correctly wait for the end of the transition to reopen the drawer on the correct channel/view. Also fixes a bug when previous URL was `/` and causing a double transition.
