Add OnUserQuit() callback. On smartphone, user doesn't want to see
same lines repeatedly. But, meanwhile, user doesn't want to miss lines
when connection was lost.
To do it, this uses OnUserQuit() callback. With this callback,
clearbufferonmsg can clear buffer if user quited client explicitly.
And when connection was lost, buffer is still not cleared.
This removes the following module hooks:
OnConfigLine()
OnWriteConfig()
OnWriteUserConfig()
OnWriteChanConfig()
Modules could use these hooks for writing/reading their own stuff to/from
znc.conf. However, no module (ever?) did this and IMHO no module should ever do
this either. Modules can save stuff via SetNV(), module arguments (SetArgs())
and in their GetSavePath().

Old modperl had several flaws and was very outdated.
New modperl makes the whole ZNC API accessible from inside perl.
Modperl API was changed, so old perl modules are not supported,
but they weren't used much anyway.
Modperl needs --enable-perl option to ./configure.
This introduces new dependence on SWIG, which is needed only while
compiling ZNC. So to use modperl, you need to install SWIG or
to download several files and use --disable-swig option of configure.
