- Administrators now get properly notified about uncompiled global scripts and the inability of the sieve plugin to store global binaries.
- Improved binary load/save error handling and fixed a few smal bugs.
- Simplified ManageSieve error handling.

Made sure that scripts are only recompiled when the script file - or the symlink pointing to it - is strictly newer.

Fixed code emission for extension-defined variables and removed hardcoded paths from include extension.
