Masterview devel - Jul 2006 - Proposed name/structure of config setting for asset path refs

Jeff - ok, here''s a proposal for config settings to specify how to
identify
the design-time directory ref prefix on image/stylesheet/js assets.

Config setting name ''template_asset_base_ref_pattern'',
structured as a hash
with keys :images, :stylesheets, and :javascripts per the standard naming
convention in rails public dir for these assets.  

The defaults for these are your xxx_SRC_EXTRACT_REGEX''s in the asset
helper
directives that match ugly rel refs up from app/views to rails public dir
(../../../public/stylesheets/xxx.css)

I like one config setting with hash entries rather than proliferating a trio
of new settings names.  Partly because I think we may need a matching config
setting for handling customization of the dir names in the public dir, but I
need to revisit that area of rails first to review the mechanics - you can
if you choose rename your public/stylesheets dir to, say, public/styles.

See javadoc below; will add this to the config doc and settings
example/gen-templates after names are settled on.

template_asset_base_ref_pattern	

Regex pattern specifications for identifying the base directory on asset
references in a template document to convert design-time assert references
for images, stylesheets, and javascript files into relative references for
use with the standard Rails asset helper functions.

Asset types are :images, :stylesheets, :javascripts

The standard patterns match path prefixes up through public/asset-type. For
example, an mv:stylesheet_link directive of the form:

  <link rel="stylesheet" type="text/css"
href="../../../public/stylesheets/mystyles.css"
mv:stylesheet_link="" />

would match the standard base-dir prefix and result in:

  <%= stylesheet_link_tag "mystyles" %>
