Minetest developer meeting 2017-05-13

Old business:
 * Additional hooks for inventory manipulations callbacks (#4035)
   * Krock was working on it (#5647), but had an issue with a mysterious crash bug.
   * > No progress
 * Timed move (#1489)
   * Merge/close?
   * > nerzhul: close for me
   * > nore: Merge
   * > Krock: Merge
 * Split block position in SQLite3 database (and use R*Tree) (#1845)
   * Rebased, performance tests to do soon(tm).
   * nerzhul: performance is a little bit slower, but it's ridiculous compared to mapblock deserialization part (no bench to show it atm, but i did it 2 years ago on my fork, and SQLite was improved since this date)
 * Add list_predict formspec element (#1988)
   * sofar worked on a rebase a while ago.  Close or merge a modern version?


New business:
 * New screenshots for website (web#78)  https://github.com/minetest/minetest.github.io/issues/78
   * ShadowNinja: "good" screenshots are fairly subjective and it doesn't look like we're actually getting anywhere near a decision in the issue thread, therefore I propose assigning someone to choose and install new screenshots.
 * Fix 'alpha' property for liquid nodes (#5494)
   * > paramat testing.
 * CSM: Fix undocumented API calls (#5756)
