Database: make conversion & helmert_transformation updatable views
- Transform conversion as a view, and when inserting into it, actually
insert into 3 tables: conversion_table, conversion_method and conversion_param,
so that method and parameter names are not repeated each time.
- Similarly for helmert_tranformation, insert into helmert_transformation_tabl
and coordinate_operation_method.
This reduces the db size from 6 344 704 bytes to 5 853 184 bytes, without
significant slowdown for queries.
