[Patch] Update religion presets and element styles

[Claudius]

This patch:

1. will add two icons to the standard element styling for places of worship for two religions that have ​more than 100 object occurances according to Taginfo already: tenrikyo and cunfican
2. updates the denominations values to cover ​today's top 20 denominations according to taginfo.
3. replaces the religion value of unitarian with the established and variant documented in the ​OSM wiki about religion unitarian_universalist

The map icons originate from PD wikimedia symbols:
