Invoice PDF formatting is messed up

[AnomalRoil]

Firstly, the address of the invoices is taking too much space: it seems to be hardcoded as being 140% of the fontsize.

truffe2/truffe2/accounting_tools/templates/accounting_tools/invoice/pdf.html

Line 121 in 27f1e2b

<div style="margin-left: 12cm; font-size: 140%;">

It would be better to reduce it to something more palatable, currently the address, date and place are taking a third of the page if you have 4 lines of address, and are really bigger than the text in the invoice.

Also, there is no need for two new lines here:

truffe2/truffe2/accounting_tools/templates/accounting_tools/invoice/pdf.html

Line 240 in 27f1e2b

<br /><br />

One would be plenty enough.

Also if you have a signature, it almost always causes the PDF to have 2 pages, because of the unnecessary number of <br /> in the div:

truffe2/truffe2/accounting_tools/templates/accounting_tools/invoice/pdf.html

Lines 251 to 256 in 27f1e2b

	<br /><br />
	{{invoice.sign|linebreaksbr}}
	<br />
	<br />
	<br />
	<br />

And having the greetings on page 1 and the signature on page 2 looks really strange.
