Simplify configuration

[nolanlawson]

Currently the XML configuration contains a lot of boilerplate (e.g. this example). A suggestion was made to change it to something more simplified, such as:

<queryParser name="synonym_edismax" class="solr.SynonymExpandingExtendedDismaxQParserPlugin">
  <str name="defaultDict">english</str>
  <lst name="dictionaries">
    <lst name="english">
      <str name="fieldType">synonym_type_en</str>
      <str name="useForFields">title *_en</str>
    </lst>
    <lst name="addresses">
      <str name="fieldType">synonym_type_addr</str>
      <str name="useForFields">street city state</str>
    </lst>
  </lst>
</queryparser>

Probably we still need some way to specify some of the parameters (such as the shingle sizes), but I can choose some sensible defaults such that most of the parameters wouldn't be necessary.

I've started to investigate this - think it is not too much work, have much of it wired already. Planning to support both old and new config format for some time.

Sounds great. Maintaining backwards compatibility, so that folks can upgrade without thinking about it, is awesome.

By the way, I've made you a collaborator on this project. I'll try to contribute when I can, and I'll let you know before I start on a particular issue, so that we don't step on each other's toes.
