Are these useful changes to the documentation for SolrPlugin?

The new install process is far easier, and the documentation is much clearer, but there are some issues that aren't mentioned that I ran into that might be relevant to others:

In foswiki 1.1.9 I couldn't get ./rest /SolrPlugin/search to work. It returns ERROR: (405) Bad Request: REST denied
In /bin/configure, I had to set {StringifierContrib}{CharSet}{pdftotext} to utf-8, which it wasn't originally, and it's burried in expert options. This caused problems for some, but not all, pdf files.
In /bin/configure, I had to set {Site}{CharSet} to utf-8, which it wasn't originally. This was causing errors for some, but not all, xls files. Strangely, if this is left empty, .solrindex returns encoding ' ' unknown.
It seemed that certain ./solrindex hangs during testing would leave working/htpasswd.lock locked. I just deleted it and let it be re-created.
