[ADD] Add fields to model templates

[chermed]

Inspiring from Rails model's generator,

If we type in the fields questions :

user_id:Responsable:compute:store:inverse name:required date:date:readonly description:text:required:compute:store:readonly:invisible:nolist:notree user_res_id:required:res.users:::me, type sequence:noform state:drat,confirm,done,cancel date_creation:today,:date:search company_id:company, product_id:nocopy:translate

We will get :

`

@api.multi
@api.depends() #TODO
def _compute_user_id(self):
    for obj in self:
        obj.user_id = False #TODO

@api.one
def _inverse_user_id(self):
    if self.user_id:
        pass #TODO
user_id = fields.Many2one('res.users', string='Responsable', store=False, compute='_compute_user_id', inverse='_inverse_user_id', )
user_res_id = fields.Many2many('res.users', string='User_res_id', required=True, default=lambda self: self.env.user, )
sequence = fields.Integer(string='Sequence', )

@api.multi
@api.depends() #TODO
def _compute_description(self):
    for obj in self:
        obj.description = False #TODO
description = fields.Text(string='Description', readonly=True, required=True, store=True, compute='_compute_description', )
company_id = fields.Many2one('res.company', string='Company_id', default=lambda self: self.env.user.company_id, )
state = fields.Selection([(u'drat', u'Drat'), (u'confirm', u'Confirm'), (u'done', u'Done'), (u'cancel', u'Cancel')], string='State', readonly=True, default='drat', )
product_id = fields.Many2one('product.product', string='Product_id', copy=False, translate=True, )
date = fields.Date(string='Date', readonly=True, )
type = fields.Char(string='Type', )
date_creation = fields.Date(string='Date_creation', default=lambda self: fields.Date.today(), )
name = fields.Char(string='Name', required=True, )

`

If accepted, I will make a mini documentation on how to use it 🎱
