Subject: Redo EventRelation; deprecate RelatesTo

RelatesTo and EventRelation have been two means to the same end in two
different contexts. (Modernised) EventRelation is the one used now both
for ReactionEvent and EventContent::TextContent. The modernisation
mostly boils down to using inline variables instead of functions to
return relation types and switching to QLatin1String from const char*
(because we know exactly that those constants are Latin-1 and
QLatin1String is more efficient than const char* to compare/convert to
QString).
