Sam Saffron 7068b58e85 PERF: flush topic timings less frequently
This is a first step of a performance optimisation, more will follow

Previously we did not properly account for previously read topics while
"rushing" marking times on posts.

The new mechanism now avoids "rushing" sending timings to server if all
the posts were read.

Also to alleviate some server load we only "ping" the server with old timings
once a minute (it used to be every 20 seconds)
