compile with new boost (1.44+)

[Karol Trzcionka]

At now users with new boost library are not able to build 0ad because of error like:

../../../source/lib/file/vfs/vfs_path.h:68: error: ‘is_basic_path’ is not a template
../../../source/lib/file/vfs/vfs_path.h:69: error: explicit specialization of non-template ‘boost::filesystem::is_basic_path’

I think it might be a bug in boost but the default api will be changed soon: ​http://live.boost.org/doc/libs/1_44_0/libs/filesystem/v3/doc/index.htm "Version 3 is a major revision with many new and improved features. It breaks some Version 2 code.

Version 2 is the default version for Boost release 1.44 only. Version 3 will become the default starting with release 1.45."

The problem is the renaming of namespaces (unfortunatelly I haven't found any official info about it) and the compiler can't find "is_basic_path".

I think the attached patch will not break building with older boost (I've tested it only with 1.44).
