Title: Fix potential crash in m_rline.cpp

m_rline only called UseInterface() in the constructor, so when there was no regex engine loaded UseInterface() did nothing.
If the specifed regex engine was loaded later on this resulted in being able to unload it behind the back of m_rline and crash the server whenever the engine was accessed.
