[Priority 10] - Batch Generation of Electronic Invoice

[Tropicalrambler]

• [x] 1. Create a multiple instance doctype, where user can select several invoices on a child table. Those invoices will be members of the batch.

• [x] 2. Add button to apply validation (Submit) to sales invoices present in child table

• [x] 3. Add button to apply generation of electronic invoice signatures to sales invoices present in child table.

• [x] 4. Add functionality to Sales invoice Actions button to allow the batch validation and batch generation from there (still the multiple instance doctype must be generated because of logs)

• [x] 5. Each batch generation must carry a log section readable by user, showing messages from INFILE.
