Update clang config (#473)

* Update clang config to put H5E_BEGIN_TRY / H5E_END_TRY on separate lines, empty C++ methods on separate lines, understand that ALL_MEMBERS / UNIQUE_MEMBERS are foreach macros, and properly skip the 'config' directory in the find command without emiting a warning

* Committing clang-format changes
