Release 7.4.0: Added new property 'com.openexchange.templating.trusted' to be able to define which templates will be handled as trusted

[Guest]

The new property 'com.openexchange.templating.trusted' located in templating.properties is used to enable the administrator to define trust for templates. This will give trusted templates more possibilities, e. g. they might not be filtered.

The property should have one of the following values:
- true: all templates will be handled as trusted
- false: no template will be handled as trusted
- server: only server templates will be handled as trusted
- user: only client templates will be handled as trusted

The default value of this property is 'server'!
