Added configuration options and multiple naming schemes

I've added default configuration options for the following options:
* size
* alignment
* default namespace
* name

Added the following naming conventions:
* `<root> : year-month : <name>-year-month-day`
* `<root> : year : month : <name>-year-month-day`
* `<root> : year : month : day`

Added support and configuration options for the use of the [newpagetemplate plugin](https://www.dokuwiki.org/plugin:newpagetemplate)

added the basic dutch language file
