clang-format with Microsoft rules

[frank-weindel]

This PR strictly contains updates made by clang-format aside from the addition of a .clang-format file.

These rules seem to work well with existing comments and gets rid of the funky curly brace style once and for all for something much saner.

Sorting of includes had to be turned off since the order of them matters to the compiler.
