Version 4 rc1 (#6)

Changes in this version:
- **BREAKING CHANGE**: All `*byField`/`*ByField` functions are now `*byFields`/`*ByFields`, and take a `FieldMatch` case before the list of fields. The `Compat` namespace in both libraries will assist in this transition. In support of this change, the `Field` parameter name is optional; the library will generate parameter names for it if they are not specified.
- **BREAKING CHANGE**: The `Query` namespaces have had some significant work, particularly from the full-query perspective. Most have been broken up into the base query and modifiers `by*` that will combine the base query with the `WHERE` clause needed to satisfy the criteria.
- **FEATURE / BREAKING CHANGE**: PostgreSQL document fields will now be cast to numeric if the parameter value passed to the query is numeric. This drove the `Query` breaking changes, as the fields need to have their intended value for the library to generate the appropriate SQL. Additionally, if code assumes the library can be given something like `8` and transform it to `"8"`, this is no longer the case.
- **FEATURE**: All `Find` queries (except `byId`/`ById`) now have a version with the `Ordered` suffix. These take a list of fields by which the query should be ordered. A new `Field` method called `Named` can assist with creating these fields. Prefixing the field name with `n:` will cast the field to numeric in PostgreSQL (and will be ignored by SQLite); adding " DESC" to the field name will sort it descending (Z-A, high to low) instead of ascending (A-Z, low to high).
- **BREAKING CHANGE** (PostgreSQL only): `fieldNameParam`/`Parameters.FieldName` are now plural. The function still only generates one parameter, but the name is now the same between PostgreSQL and SQLite. The goal of this library is to abstract the differences away as much as practical, and this furthers that end. There are functions with these names in the `Compat` namespace.
- **FEATURE**: In the F# v3 library, lists of parameters were expected to be F#'s `List` type, and the C# version took either `List<T>` or `IEnumerable<T>`. In this version, these all expect `seq`/`IEnumerable<T>`. F#'s `List` satisfies the `seq` constraints, so this should not be a breaking change.
- **FEATURE**: `Field`s now may have qualifiers; this allows tables to be aliased when joining multiple tables (as all have the same `data` column). F# users can use `with` to specify this at creation, and both F# and C# can use the `WithQualifier` method to create a field with the qualifier specified. Parameter names for fields may be specified in a similar way, substituting `ParameterName` for `Qualifier`.
