Update app icons container slidedown speed

Ain't nobody got time for that

Do you have a long list of containers + vms?

Further investigation shows that the DockerClient.getAllInfo() method takes more than 2000ms to complete on the 32 container instance I'm running. Further delaying the slideDown speed makes it unpleasant to watch.

Commenting out https://github.com/limetech/webgui/blob/fa8b4a931b01142ada2c2c02fa101cd52ac0a30e/plugins/dynamix.docker.manager/include/DockerClient.php#L327-L341 produces a consistent loading time reduction for DockerClient.getAllInfo() by about 1800ms.

For 32 container instances DockerClient.getIcon() takes about 150ms, DockerClient.getControlURL() about 1150ms and populating $Registry, $Support, $Project takes about 400ms. DockerClient.getTemplateValue() seems to be going through all template files every time it's being called. Perhaps load that data into memory and retrieve from there instead.

My case:
I have 9 containers + 3 VMs. The complete rendering takes 517 ms.
Your hardware plays a role too!

@bergware, figured out it is actually 32 containers with 21 being on. Wonder what would be a good way to speed this up. Is /usr/local/emhttp/* living in tmpfs @limetech?
