Remove plugin references from funktionen.conf (or move important ones over to wollmux core)

[thorstenb]

Current sample config hits errors for a number of pre-configured templates (like external or internal letter heads):

de.muenchen.allg.itd51.wollmux.config.ConfigurationErrorException: Script "java:de.muenchen.allg.itd51.wollmux.func.Standard.formatiereTelefonnummerDIN5008Intern" not available

de.muenchen.allg.itd51.wollmux.config.ConfigurationErrorException: Script "java:de.muenchen.allg.itd51.wollmux.func.Standard.zahlenBereich" not available

Code for that is in .wollmux/config/plugins/de/muenchen/allg/itd51/wollmux/func/Standard.java but at least the phone number functions openly admit to be Munich-specific.

My take:

• split wollmux config into sample (or example) bits, and core config
• cleanse sample templates from any custom functions
• move generally useful stuff (like regexp, zahlenBereich (after translation)) into Wollmux core

But whatever sits in the default wollmux-config archive should be running w/o errors out of the box.

This is to say, the plugin concept is useful & powerful, and should be retained. Reference to plugin functions should be relegated to either documentation, or 'sample config' that is not part of the default config archive
