More changes for mindtouch scraper

[benoit74]

Changes:

• fix repr of ZimPath / HttpUrl which where too long and not working
• add support for no pre_head_insert in html rewriter and no js_notify callback in all rewriters
• instead of build items_to_download in the rewriter, return complete url rewrite information so that 'users' (e.g. mindtouch scraper) can decide what they want to do

Nota:

• this has been tested with upcoming changes for mindtouch scraper and is supposed to be feature-complete. In last (and biggest) change, the signature of rewriters are not significantly modified so it is not expected to cause significant changes in warc2zim once we will start Move to zimscraperlib content rewriting warc2zim#411
