Fix bug in abstract handling in ISO XSLT

Before this change, a missing abstract would still show up but just as
an empty box with on content. This should be fixed now.

- Clean up isoroot selectors and comments. Use relative xpaths when possible
- Clean up the output of the ex module
- Misc whitespace/formatting fixes

Clean up ISO stylesheet formatting

Start the basis for gmd:distributionInfo

Minor tweaks and code cleanup to ISO XSLT

- Renamed the folder once more to be more correct

Multiple changes to the ISO XSLT

- Renamed base folder from iso to iso19139
- Added a short_citation template for showing thesauri in tight places such as the keywords list
- Tweaked the geographic coverage output so the static maps render in Metacat UI

Continue work on ISO XSLTs

- We now have a template for CI_Citation
- I moved some templates into separate XSLTs
- Cleaned up overally structure/styling of translated output

Include the files that were totally supposed to go in the last commit

Continue work in ISO XSLT

- Tweak how extents are displayed
- Start adding support for GML Polygons
- Restructure EX module templates and clean them up a bit

Continue work on ISO XSLT

- Cleans up the root element to better match what we want in the end (looks like the EML XSLT)
- Switches a lot of calls to call-template over to apply-templates. I think this is a good idea because the ISO standards use XSD type equivalence to extend existing schemas. e.g., gmx:Anchors can show up when the gmd schema says only a gco:CharacterString should go there...
