[FIX] website_twitter: IE does not accept twitter date format

Datetime like Tue Jul 13 23:18:36 +0000 2010 is not accepted by IE and return "Invalid date".
Therefore, We parse the date to a format known by IE (and other browsers)
Trick took from http://stackoverflow.com/questions/3243546/problem-with-javascript-date-function-in-ie-7-returns-nan
[FIX] point_of_sale: invoicing in the pos printed the wrong order due to a mismatch between order ids and invoice ids

[IMP] models: improve code of _convert_to_write(), make it easier to read

[FIX] mrp_operations: use list instead of record set for o2m

In v7, accessing a o2m returned a list of browse record while it returns a recordset in v8.
The method _move_pass expects a list so a manual conversion is required.
Fixes #1787

[FIX] account_voucher: avoid error if no partner

The field partner_id is not required on an account.voucher but the validation was failing if none was set (opw 611663).
This patch makes a fallback on the account of the voucher if neither a partner nor a writeoff account is specified.
[IMP] account_voucher: make the field tax_amount always readonly

The field tax_amount is fieled with onchanges and the compute_tax method. Setting a different value than the one computed by the system may lead to unbalanced move (which is obviously wrong).
In the future, handeling these operations by setting the correct value to the tax accounts would be better.
[IMP] Cache bundles in ir.attachments instead of LRU
[IMP] website_quote: handle quote and website descriptions

Add field quote_description on product.template and turn website_description from sale.quote.line into a related.
Overwrite write and create methods to synchronise both fields when setting a product.
website_description on product.template is added by website_sale but there is no dependency relations between these modules so we need to define it in both modules.
[FIX] sale: define sale_note field before using it as a default value for sale.order

When uninstalling/installing sale module, this can be problematic
[IMP] Cache bundles in ir.attachments instead of a LRU
