update for Blacklight 3.x/Rails 3.x
Fix typo
move range limit routes into BlacklightRangeLimit::RouteSets (otherwise plugin routes are loaded after application config/routes and get lost)
No more _solr_request partial.
fix error in IE-only excanvas loader
bump VERSION  to 3.0.0pre3
remove empty no-op initiailzer using deprecated rails api too and doing nothing
include to CatalogController specifically, not Blacklight::Catalog lib/blacklight_range_limit.rb

Blacklight::Catalog was too much magic, made it load-order dependent and unpredictable. Even though it would have been less fragile design if it worked reliably, it didn't.
use new solr_search_params_logic design

SO much easier to debug.
move routes addition inside BlacklightRangeLimit.inject\!, with other auto-injection stuff, keep it together.
do not modify original params hash

or it's nested values. When generating links to removing a range constraint. modifying original data messes up rails app, since later code wants to look at #params to see the request, and you've changed it. #dup what neds #dup'ing.
don't show limit for both empty string begin/end
Merge branch 'master' of git://github.com/projectblacklight/blacklight_range_limit into rails3
use bundler tasks for gem release, 1.0.0pre1
rails3 instructions
proper blank checks for begin/end params
1.0.0pre2
guard against blank begin/end in render_to_s too
more careful check for empty begin/end params
avoid rails deprecation warning for <% form_tag, need <%=
