Reintroduce the code related to InsetEnvSeparator

Browse Source 
This commits (tries to) reintroduce properly the code that was reverted at the beginning of this branch. This had to be done because these patches interefered with the big refactoring of TextMetrics.cpp.

This commit reintroduces the changes to TextMetrics.cpp contained in c668ebf6, c85dbfea9 and 061509bf.
