[FIX] survey route that is only accessed with POST verb
[MOV] crm: moved css / js related to salesteam to sales_team module; sale_crm: moved data and demo data into
sale and sales_team module.
Merge branches 'server-saas-4', 'web-saas-4' and 'addons-saas-4' into saas-4
[MERGE] [MOV] [ADD] sales_team module holding sales team related stuff. The sales team implementation has been taken out of crm, allowing to use the sales team concept without having to depend on the crm module. crm and sale now both depend on sales_team module and add their specific fields to the model. sale_crm module has been simplified by removing sales-team related stuff. The default section id on users is now located in sales_team, not in sale_crm anymore, allowing its use in both crm and sale modules.
[IMP] gamification: avoid fetching function field while we could reuse the cache system of the browse records (avoid memory errors when updating a large number of records)
[FIX] lazy sitemap with generators
[FIX] website_blog: display blog posts in anti-chronological order
[FIX] gamification: avoid sending reports for non-reported challenges
[IMP] website: refactor website_image controller (and placeholder), move to model to make it reusable

It is "almost" reusable because it still depends on the global `request` variable,
this could be solved by making it an explicit parameter.
[FIX] website_forum: fix controllers losing paging and query params, allow to see own profile even without karma, add avatar controller to make the images public
[REV] Revert lazy sitemap
[MERGE] Sync with trunk
[FIX] website_sale: removed now unnecessary dependency
towards crm for website-sale, as sales_team module is a dependancy of sale.

Also reverted some changes in comments.
[FIX] website_sale, website_crm: website salesteam value in correct
module.
[FIX] website_forum: display it as some kind of table for better display
[FIX] website_forum: fixed commit 9426: values were badly computed for the link_button template
leading to most buttons being buggy on the forum.
[FIX] account_analysis_account: Keep price_unit to 0.0 if passed
[FIX] account_analytic_analysis: recurring invoices, product_id_change wasnt returning the price get from the pricelist
[FIX] website_partner remove controller, add support for negative ids
Launchpad automatic translations update.
