bump dev version to 0.4.8
header rewrite: pass through 'content-range' header
route selection via proxy auth!
refactor poute request parsing to happen in the actual router class instead of in the route
in proxy mode, add support for picking a route via proxy-auth
improve test for 'top' rewriting
proxy: add 'proxy_coll_select' config which will require a proxy-auth to select a collection for proxy mode.
Otherwise, defaults to first available collection, though proxy-auth can still be sent to specify different collection
rewrite: fix rel url resolution to better handle parent rel path.
Explicitly resolve path when possible, remove only if at root level
rewrite: better fix for multiple ../ in urls, additional tests
cookies: support client side rewriting of document.cooke -> WB_wombat_cookie to rewrite cookie path, if present
cookie: add test for 'document.cookie' rewriting
live-rewrite-server: add ability to specify http/https proxy for live fetching
(for example, for use with a recording proxy)
memento: use mp_ modifier to support memento with frame or non-frame replay
change memento test to use frame replay
live handler: allow live rewrite handler to be specified as one of the collections in pywb
by settings index_paths to '$liveweb'. When used, creates a RewriteHandler instead of WBHandler
Can also specify 'proxyhostport' to set the live rewrite to go through a proxy

fallback: allow fallback to a different handler (usually live rewrite) by specifying
'redir_fallback' with name of handler. Instead of 404, a not found response will
internally call the fallback handler to get a response
handlers: change 'redir_fallback' to 'fallback' as no redirect happens, fallback
called internally
cdxindexer: when indexing entire dir, only look at files with ext .warc.gz, .warc, .arc.gz, .arc files
and skip the rest. (Files with other ext may be specified explicitly)
replay ui: improvements to framed replay messages.
'is_live' added to live rewrite to allow for different message for live replay
vs archived replay to be used.
When using framed replay, default initial message to 'Loading...'
default index.html: list non-replay access points in default home page
update version to 0.5.0, update CHANGELIST and README
fallback: better way of setting fallbacks, check for 'resolve_refs' method on the handler
and pass handler_dict if one exists
tests: add integration tests for $liveweb rewrite handler and replay
with fallback
pep8 cleanup pass
