Fixes #428, Fixes #429. This reverts `FieldComparer` to be closer to the Java implementation, which uses reference type wrappers for numeric value types so it is not so expensive to unbox them when placed in an `object[]` array. Note that the tests were all converted to use the fastest syntax to unbox the number: ```c# int value = (J2N.Numerics.Int32)objectWrapped; // Implicit conversion to System.Int32 int value2 = ((J2N.Numerics.Number)objectWrapped2).ToInt32(); // Explicit conversion from unknown reference numeric type to Int32 ``` Although slower, using `Convert` methods are less verbose and more consistent: ```c# int value = Convert.ToInt32(objectWrapped); // objectWrapped2 is J2N.Numerics.Int32 int value2 = Convert.ToInt32(objectWrapped2); // objectWrapped2 is unknown subclass of J2N.Numerics.Number ``` There are also several other updates: - J2N parsers and formatters are used to convert to/from strings (these patch the broken floating point round tripping back to .NET Framework and change the default format to always include at least one place after the decimal point) - NumericRangeQuery<T> was also modified to eliminate boxing that was introduced by using `Convert.ToXXX` methods on generic value types. - Use `HasValue`/`Value` on nullable value types to reduce casting - Use `Nullable.Equals()` for comparing generic numeric types for equality - `Lucene.Net.Queries.ObjectVal` returns a `J2N.Numerics.Number`-derived type rather than a value type cast to `object` - **BREAKING:** `Lucene.Net.Search.FieldCache.IParser::TermsEnum()` Renamed method to `GetTermsEnum()` to match other APIs -- This is an automated message from the Apache Git Service.
