Update README_TOMCAT.md

I configured AS on Windows using Tomcat 7.0 but I had to install to a directory without spaces to make it work.
Use matching bundler version for plugins

If the version of bundler that gets installed in a plugins gems
directory does not match the version shipped with ArchivesSpace
then ArchivesSpace fails to start.

Explicitly setting the bundler version in initialize-plugin.sh to
match the version in the archivesspace gems directory resolves
the issue.

This will also to need to be done for initialize-plugin.bat
Use a variable for the logs location

This makes it easy to change the default logs location by setting
an environment variable or rewriting the value in the startup
script.
Update docs where logs location is mentioned
Add links in footer to frontend and public interfaces

From the frontend if the public interface is enabled add a link
to it in the footer. Do the same for the public interface if the
frontend is enabled (add frontend footer link).

The feedback plugin overrides the footer so that is updated also.
