PDF viewer (preview) 6.x - 10.x

Detailed description of the features :
Once activated, the module will automatically split the listing in two for displaying the viewer according to the defined user settings.
Indeed, each user will have the possibility to indicate if he wishes, or not, to opt for this display by default. When arriving on a listing, when hovering over a line, the module will display the concerned PDF.
The user can also scroll through the PDFs using the keys on his keyboard. On each listing, a button will also activate / deactivate the display of the viewer temporarily (this parameter will be the default configuration for the next display of this listing).

The module allows to display the viewer on the following listings:
- Customer quotation      - Supplier quotation        - Customer Invoices
- Supplier Invoices          - Customer Orders         - Supplier Orders (> = 9.0.2)
- Expedition                      - Intervention                  - Expense Reports (> = 9.0.2)
- Contracts (> = 9.0.2)
