pavelxdd 7e68068c25 fix compilation with boost::filesystem ...

CMakeLists.txt:
---------------------------
Until now build with boost::filesystem was completely broken,
since cmake exported definitions with wrong name prefixes, and
nana always defaulted to internal filesystem implementation.

After fixing the boost definitions, a number of errors came up
due to incompatibility of boost::filesystem with nana and std
filesystems. This commit tries to fix them all.

filesystem.cpp, filesystem.hpp, filebox.cpp:
--------------------------------------------
boost::filesystem doesn't have a file_time_type, so declared
it in the filesystem.hpp header.

boost::filesystem::last_write_time has a return type std::time_t
unlike the other two implementations of this function in nana
and std, so added ifdef to convert the result to file_time_type.

fixed build on gcc-4.9, since it doesn't have a std::put_time
function, included <nana/stdc++.hpp> in that case.

boost::filesystem::file_type types have different names than
std::experimental::filesystem::file_type types, fixed it by
creating an enum class file_type with the same type names as
in std::experimental::filesystem::file_type. This fix
requires static_cast from functions results to internal file_type,
since boost file_type and std file_type a different enum classes.

changed switch to if, bacause old gcc fails on converting
enum class members to int.

stdc++.hpp:
-----------
added ifndef guards to prevent errors on multiple includes of this header.

wvl.cpp:
--------
added boost/chrono.hpp include for the cases when std::thread is not
available.

travis:
-------
added boost system, thread, chrono libs to install, they are needed
for the nana-demo to compile.
