Default configuration file in b2g4pipe_v2.5.zip is out of date.

During automated installation, make a copy of b2gPipe.properties
using the current latest settings as per the website page
http://www.blast2go.com/b2glaunch

i.e.

Database settings for Blast2GO Basic
The database server is: publicdb.blast2go.com
The current public database is: b2g_aug12
Get TravisCI to install b2g4pipe v2.5
Get TravisCI to test Blast2GO wrapper

Assuming the install etc works, I am expecting this to fail as
the http://www.blast2go.com/data/blast2go/b2g4pipe_v2.5.zip
file ships with an out of date default configuration file
pointing at a Blast2GO database which doesn't exist anymore.

For both TravisCI and automated installation via the Tool Shed
this will require patching the default configuration...
Blast2GO needs Java; was missing a symlink
Try running this as a Java build on TravisCI
Use August 2012 Blast2GO database under TravisCI

The default b2gPipe.properties file shipped with b2g4pipe v2.5
points at an old database and hostname which don't work anymore.
We therefore copy this default configuration and then update the
database name and host using sed.
