BUG: Prevent Boost from compiling libraries and Fix windows compilation errors

## Commits

- `BUG: Prevent Boost from compiling libraries (ANTS only needs the header-only components of boost)`  
In file SuperBuild/configureboost.cmake:  
The option "--with-libraries=" in boost/bootstrap.sh sets the list of libraries to compile to an empty string, which has for consequence to compile ALL boost libraries, so the opposite of what we want.  
To fix this, I used the other option --without-libraries which allow to prevent boost from compiling all libraries by giving all their names:  
`--without-libraries=atomic,chrono,context,date_time,exception,filesystem,graph,graph_parallel,iostreams,locale,math,mpi,program_options,python,random,regex,serialization,signals,system,test,thread,timer,wave`  
The names of the libraries are then hard coded, but this is not an issue, as the ANTs SuperBuild downloads a certain revision of boost. It will just be necessary to update this list whenever a different version of boost is used in the SuperBuild.  


As I tried to compile ANTs on Windows, I encountered several issues:

- `COMP: Add boost compilation commands for Windows`
On Windows, the command to be ran to configure boost is bootstrap.bat and it does not allow options.
Therefore, the --prefix option and all the --without-<library> arguments are given to ./b2 when building.

- `BUG: Fix windows compilation errors`
Some code did not compile on Windows, I propose an alternative solution for each of the errors.
NB: I was not able to fix one of the errors in the External Applications, so the windows build has compiled without the external applications built:
In file [ExternalApplications/MALF/CorrectiveLearning/segAdapter.cxx](http://github.com/adrienkaiser/ANTs/blob/master/ExternalApplications/MALF/CorrectiveLearning/segAdapter.cxx#L330-L331)

```

There was also a missing cmake argument in the inner build external project declaration ([BUILD_EXTERNAL_APPLICATIONS](http://github.com/adrienkaiser/ANTs/blob/master/SuperBuild.cmake#L284)), which made the External Applications compile even with the option set to OFF.
