Reduce the fadeout delay of the Loading indicator.
The Loading indicator was given a 1 second delay in order to not just

flash on and off on some requests, so that users can see that their

request had indeed started and finished.
1 second is a while, so this drops it down to 250ms. Testing with my

local server, it was on the screen just long enough to show the request

started and completed, but short enough to feel like the request

finished quickly.
This should give the perception of a large speed boost.

Tested with some local requests. Everything felt much faster.
