Subject: [PATCH] update mysqldump, add imapsync

* remove useless --skip-lock-tables option for mysqldump, already set by --single-transaction
* set gzip compression level to 1 instead of 9 : backup process is two times faster, but dump size is only 15% higher
* add imapsync script, installation instructions will be added soon
