Added RandomCharSequenceGenerator.
Added XML documentation to RandomCharSequenceGenerator.
Made RandomCharSequenceGenerator the default builder for characters.
Modified RandomCharSequenceGenerator to request a random 32-bit signed integer instead of a 64-bit signed integer.
Addressed a Code Analysis warning.
Removed a test that could behave erratically.
Incremented patch version,

in order to indicate a fix. Actually, one could argue that the change of
behavior in how chars are generated constitute a breaking change, but this
change is being made while the current public version of AutoFixture is
2.16.2, and is being made on the v3.0 branch, so it will be included into
a version which already collect a lot of breaking changes.
Since it's not really a new feature either, incrementing the patch version
seems most reasonable.
