Usually there is the need to show the company logo on printed reports, so it will be great if we add some fields on company to allow the user to customize it. In trytonspain there is a module  which add the logo as Binary field, so the idea is to include in base at least this fields:
- logo: field.Binary
- width: field.Integer which stores the logo width
- height: field.Integer which stores the logo height
We can also change header and footer to HTML fields, but we first need to solve issue2068.
Do you think more fields are needed?
Do you think that this information can be reused for other usages?
