Fix: freeing previous elements has to be done before loading new parameters to avoid trying to delete unexisting objects if arrays size was modified

When a cluster is empty for KMeans, it's better to give it the point from another cluster j that is the furthest one from center j.

Silenced a few -Wcast-align warnings in the headers.
...
We don't use -Wcast-align ourselves, but the headers trigger warnings
for those users who do, which is not nice.

Fixed a bug in FLANN resulting in uninitialized accesses.
...
This is fixed upstream in mariusmuja/flann@b615f26 , but that fix
would break binary compatibility, so I had to make a different one.
Since the bug isn't quite obvious, here's an explanation. In the const
version of any::cast, if policy is a small_any_policy, its get_value
returns its input argument. So r becomes a pointer to obj, and the
return value is a reference to a local variable, which is invalidated
when the function exits.

Looks like we don't actually use them; when creating precompiled headers
with Visual C++, a dummy .cpp is created at build time.

fixed possibly inccorrect interval measurements in flann's timer (bug #1165 ). Note: this may break binary compatibility, but since the class is not wrapped in Java and not exposed in Windows API, for example (it's considered internal-use class for flann), the effect should be minimal
