- With this change screenshot file names have the following pattern:
save file name +  + YYYY-MM-DD hh-mm-ss + .png

- To get the correct date and time the method platform_get_time and platform_get_date are rewritten and to a version for UTC and a version for local time. This change gave the opportunity to simplify the code generating file names for autosaves.

- SOUND_WINDOW_OPEN is now the new "shutter" sound when taking screenshot.
