Replacing svn(1) with svnlite(1) in manpages and documentation

[Mateusz Piotrowski]

Hello,

It looks like some users find it confusing that the documentation speaks of
using svn although it is not present in the base system.[1]

I can think of two solutions to this problem:

1. Link /usr/bin/svn to /usr/bin/svnlite and use svn consistently throughout
   documentation. 

   This solution might turn out to be confusing whenever svn from ports is
   installed and /usr/bin is earlier in PATH than /usr/local/bin.

2. Use svnlite consistently throughout documentation. 

   Some manpages like development(7) have already switched to using svnlite in
   their examples. 

Personally, I'd go for the second solution. Can you think of any potential
problems we might face?

Regards,
Mateusz Piotrowski
