[IMP] expenses: ref content to top-level TOC page

This commit is part of a larger work to improve the documentation's
structure. The toctree structure used to add levels to create categories
and make the structure visually more understandable.
With the new version of the documentation, plenty of these categories
are now redundant.

This commit:

- renames "expense" to "expenses" as it is in the app and in the title
- restructures the files
- moves the media files from "media" folder to "expenses" folder
- adds a short intro to expenses

 How to set expense types
 ========================
+
 The first step to track expenses is to configure the expense types (managed as products in Odoo)
 that your company allows, from the *Configuration* menu. 
 When a specific expense is reimbursed at a fixed price, set a cost on the product.
 Otherwise keep the cost at 0.0 and employees will report the real cost per expense.
