Predefined filters

[giner]

Would be helpful to be able to keep predefined Tcl filters in apt-dater.conf in order not to copy-paste them from somewhere each time when they are needed.

Hi,

this sounds like a reasonable enhancement. The config file should allow a name => Tcl filter expression mapping. While select Tcl filters in apt-dater the user should be able to select one of the predefined definitions by a list of their names.
