Empty entry in \tableofcontents in case e.g. section without description

Generate error message in case bibtex generation fails

In case a section, subsection etc just has a tag and not a description in the \tableofcontents there is nothing mentioned. With this patch the tag is used as description when no description is present, as is done on other places as well (consistency and no empty items in the \tableofcontents).

In case bibtex fails no message is given. When perl is missing the OS just emits an message. With this patch doxygen logs a message (analogous to other calls to portable_system)

Fix bug with C++11 static_assert

When processing a C++11 static_assert, we wish to skip the arguments. However, the `roundCount` is set to 1 despite the fact that the `SkipRound` routine will increment `roundCount` when it's entered. This causes the rest of the class to be skipped entirely.
