replace-table: Add support for custom functions

This adds a support for custom (registered) functions that can be called
from templates with specified arguments.

The syntax is as follows:

<!-- $(function_name(arg1, "arg2", 'arg3')) -->

Arguments are separated by a comma and can be quoted (recommended).
Quoted arguments are allowed to contain a comma as well as another
quote when escaped with a backslash.

To call a function with no arguments just do "function_name()".

Functions are supposed to be registered before actual data are parsed
and are called back from within the parser cycle.
