my little forum 2.4.9, maintenance release

Attention: This version only works with PHP versions up to 7.2.x!

In case of an update: This version can only be an update target for existing installations from version 2.3.5 upwards!

Fixes

• fixed: use the function get_avatar also in the admin panel, used before only the code for the old file name scheme which leads to only displaying avatars with names in this old name scheme
• fixed: avatar field in the user data form of the admin panel had no label because of missing string in the language files
• fixed: adapt changed URL-parameter behaviour for folding threads to the JS-sources, didn't work with the switch instead the toggle
• fixed: changed long date format for german language to month as number with leading zero, out written month name "März" can cause encoding problem on some servers
• fixed: the deletion of entries about read postings was broken in the case of deletion after X days, used the old and removed setting name read_state_expiration_date instead read_state_expiration_value

Feature

• added: put pixel dimensions of uploaded images into the HTML source, when included in entries, prevents page jumping during load process for only this case(!)

Changes

• added: sentences about automatic generation of e-mails to inform about new entries, user, etc., a few users answered to these automatic messages
• added: make the mouse cursor a hand (pointer) when hovering over a (visible) label element
