Pull request 55 (thanks: haeal), with some tweaks; better handling of shutting down the data-reader on the happy path

Applied partial to all Dapper classes and interfaces in order to improve extensibility

Multi-Mapping issue with SplitOn

Dapper by source to extend the Dapper classes without making changes to
the Dapper source (for instance in order to expand DynamicParameter with
a method HasValue<T>(string name)). In addition to further help developers
that reference Dapper by source the public property of Dapper classes are
moved to separate partial classes. By default the previous behavior is kept
but when referencing by source you can now make the Dapper classes internal
by defining: DAPPER_MAKE_PRIVATE

There was a small issue when SplinOn spaces between commas, for example:
splitOn: "AddressId, Id".
For more info see:
http://stackoverflow.com/questions/11042618/dapper-multi-mapping-issue

I have modified below line of code:
From: var currentSplit = splits[splitIndex];
To: var currentSplit = splits[splitIndex].Trim();

Also added a test called:
TestMultiMappingWithSplitOnSpaceBetweenCommas()

Ensure that when processing bools we do a "!=0" test; we don't just want to store `7` as a bool - that causes problems sometimes.

Minor deploy glitch (should now include intellisense files!)

Fixed issue with incorrect generated ParamReader when it has indexing properties declared.

IL level type-remapping, so i8 / i4 are interchangeable, etc. This avoids issues on databases that return 1 as bigint by default, etc

Support of types for Id column in Dapper.Rainbow

From time to time ID column has types different to int. With this change
you could specify column type if it is different to int. Example:
public Table<MyDb, Guid> Users { get; set; }

Minor tweaks to custom type-map implementation; principally, lock-less reading and caching the default type-map

Conflicts:
	Dapper.Rainbow/Database.cs

tweak tests to represent this (and workaround)

Added [ActiveTest] to allow trivial debugging individual tests

Replicated a bug 'Dapper MultiMap doesn't work with splitOn with NULL value'

Fix for issue #70 (support for TimeSpan)

Added dynamic query like for CSharp30.

Also optimised ldloc/lodloca/stloc and fixed enum double-assignment

Fix for issue #70
(http://code.google.com/p/dapper-dot-net/issues/detail?id=70) and also
related MS bug with DbType.Time
(https://connect.microsoft.com/VisualStudio/feedback/details/381934/sqlparameter-dbtype-dbtype-time-sets-the-parameter-to-sqldbtype-datetime-instead-of-sqldbtype-time).

Capitalize "id" to maintain consitency

sql_variant support query parameters and SQL Server
