This patch attempts to add proxy config support to NeoChat so people could set a HTTP or Socks5 proxy for anonymity or privacy/censorship-circumvention reason.
Currently this will only allows setting proxy type, host and port (which should be usable for most of the cases). Settings in that page needs to be applied by clicking the Apply button so the proxy setting won't accidentally get changed.
Proxy is disabled (use System Default option) by default.
Use animated images in imageDelegate and FullScreenImage so that animated images can be viewed.
Note webp animated images don't work this is a bug with qt see https://bugreports.qt.io/browse/QTBUG-70245
Update the base item in the timeline container to be a column layout. This means that all the items can be laid out automatically without the need to set lots of manual settings and anchoring.
The overall height calculation for the delegate is vastly simplified (in fact it is removed) which deals with the fact that there were still instances where the manual calculation didn't work e.g. a delegate with a reaction followed by another message from the same user didn't give the correct bottom margin (see below)

This also improves upon the recently changed hover highlight behaviour. The previous patched moved it to cover the avatar as well as the bubble however it also covered the section and reaction when present which didn't look good. The highlight now only covers the avatar and bubble

This also cleans up some of the margins in both bubble and compact to ensure consistency.
Set max size to gridUnits * 30. The aim is to allow them to be generally bigger than bubble mode but not so huge that they take up the entire screen
BUG: 454878
**Updated**
Add a section label at the top which shows the date label of the next section up. This means that the user will always be able to see the date of all messages on screen.
From the feedback given I've added a background at the top. I also added an underline to the heading which applies both at the top and in the listView since they use the same component. I added it originally for the top because I felt it looked a bit weird having messages appear from behind a heading background the same colour as the listView background.
Note: I know the gaps between messages are not right. I had to set the spacing in the listView to 0 to prevent itemAt returning null. I plan to add it back in as part of the delegate code before it would be merge.
Fixes BUG:454880
Initial work to create a model so that new servers can be added to the list.
The model will also check if the server is valid before allowing it to be added.
Implements network/neochat#11
