Use new logic for gathering data in MeshFreeInterpolation
Use static_assert to get a slightly better error message.
Fixed bug in SerialMesh::stitch_surfaces in the case that we stitch a sliver, e.g. imagine the fourth stitching when you stitch four cubes together.
Update references and website.

First 2015 reference.
Merge pull request #325 from libMesh/static_assert

Rearrange structures to reduce padding
Get rid of atavistic FEMFunctionBase member
Initialize more variables in constructors

This is the "watered down" version of ab47188e, with only those
initializations that should improve correctness, efficiency, and/or
ease of debugging.  Initializations that should merely make -Weffc++
whine less are now limited to the weffcpp_fixes branch.
first_solve is UnsteadySolver-only

Looks like I missed the copy in the base class when refactoring
Don't start with undefined iteration counts
Rearrange Elem members to reduce struct padding

On 64-bit machines when configuring with 32-bit subdomain ids this
ought to save us 8 bytes per Elem.
Reorder DofObject id and unique_id

In the most common case (unique id 8 bytes, id 4 bytes, processor id 4
bytes) this should save us 8 bytes of padding per DofObject
Tell -Wconversion we really want to downconvert
