Issue related to the name's .svg file.

I would like to report an issue!! :)

Software error:

------------- EXCEPTION: Bio::Root::Exception -------------
MSG: Sorry the format 'svggraph' can only be used as an output format
STACK: Error::throw
STACK: Bio::Root::Root::throw /usr/share/perl5/Bio/Root/Root.pm:486

STACK: main::bioperl_it_up /usr/lib/cgi-bin/treefix.cgi:244
## STACK: /usr/lib/cgi-bin/treefix.cgi:193

Please send any errors with a description to g.leonard@nhm.ac.uk
# An inappropriate error message; the mistake in this case is related to the name of the .svg file which can not contain any dot "." in. Just replace every dot if present!

Start with the stack locations named in the report, especially /usr/lib/cgi-bin/treefix.cgi and Bio::TreeIO::svggraph.pm, and trace how the SVG output filename reaches the formatter. Reproduce the case with a dot in the name; done means dots are replaced and the reported input no longer produces the inappropriate format error.
