Added TDS settings for Git

TDS has extra files to ignore and special line ending for .item files
Fix path to TDS assemblies

The path to the TDS assemblies was modified to a relative path. The
assemblies, however, are no longer in that location. That path as been
update to the default location as specified by TDS.
Added support for custom facets

* 'custom' facet types were unsupported!
- modify ItemBuckets.js to support the 'custom' type
- added new 'Title' to the FacetReturn object. This controls text of
facet group.
- Search.ashx.cs now will set properties on a facet from the Parameters
field of the facet item
* Prevent lucene from executing a '*' search. If only a '*' was passed
as a text search it is better to not search on this and still get the
same results.
