Rework of the XSLT used to generate the Summary CSV export:
- fixed a bug causing invalid CSV to be generated for double quotes
(`""`);
- changed quoting and escaping to be compliant with RFC 4180;
- changed output to contain information for all cylinders for all dives
(instead of limiting the number of cylinders to howevermany are used
for the last dive);
- added an index to the cylinder data headings;
- changed unit designators to use `[]` instead of `()`;
- some minor improvements to the XSLT.
