Tweak assert enable/disable behavior so the asserts still come on or off as a 

function of the release/debug drop down menu when using visual studio's IDE.

# Never force the asserts off when doing an in project build. The only
# time this matters is when using visual studio. The visual studio IDE
# has a drop down that lets the user select either release or debug
# builds. The DLIB_ASSERT macro is setup to enable/disable automatically
# based on this drop down (via preprocessor magic). However, if
# DLIB_DISABLE_ASSERTS is defined it permanently disables asserts no
# matter what, which would defeat the visual studio drop down. So here
# we make a point to not do that kind of severe disabling when in a
# project build. It should also be pointed out that DLIB_DISABLE_ASSERTS
# is only needed when building and installing dlib as a separately
# installed library. It doesn't matter when doing an in project build.
