MvsSln 2.5.3 is missing in 1.7.4

[3F]

My bad...

I forgot to update git submodule before branching. And looks like FIPS edition in 1.7.4 still is based on 2.5.2

[v1.7.4] ❌ https://github.com/3F/DllExport/blob/c1cc52fa13f563f97a2b4fe08bfb541c69195866/changelog.txt#L26-L27

Here's most important possible error for 2.5.2 https://github.com/3F/MvsSln/issues/29

It can also affect DllExport project but not sure about the importance; so just let me know about it, I'll prepare new release ASAP
