Manula software updates related to "performance"

Some small performance improvements for the live manuals have been implemented today. The topic pages now have the correct “Last Modified” headers and now respond to “If-Modified-Since” requests, resulting in proper caching behaviour in your browser.
We’re still optimizing the system, so more news on this later.

Last week, we gave the home page of your Manula admin a complete make-over.
Today we implemented several performance updates to make this page load faster.

For accounts with lots of manuals, the loading of the views & ratings charts had become quite slow, even to the point of locking up the page for a few seconds. Not anymore!

To improve the speed of your live manual pages, we have implemented a small but effective tweak to our server. All HTML documents, CSS style sheets, and Javascript files are now served in compressed/deflated form (to supported browsers only, but most modern browsers support this).

The difference in page loading speed should be considerable, especially on slower connections.
