EPUB writer:  Don't add sourceURL to absolute URIs!

Closes #1669.

If there are further issues, please open a new, targeted issue on the
tracker.  Some notes on the further issues you gestured at:

Data URIs are indeed dereferenced, but why is this a problem?
(The function being used to fetch from URLs is used for many different
formats.  Preserving data URIs would make sense in EPUBs, but not
for e.g. PDF output.  And by dereferencing we can get a smaller,
more efficient EPUB, with the data stored as bytes in a file rather
than encoded in textual representation.)

"absolute uris are not recognized" -- I assume that is the problem
just fixed.  If not, please open a new issue.

"relative uris are resolved (wrongly) like file paths" -- can you
give an example?

`<base>` tag is ignored.  Yes. I didn't know about the base tag.  Could
you open a new issue just for this?
fix inDirectory to reset to the original directory in case an exception occurs
Fixed absolute URI detection in EPUB writer.  Closes #1672.
EPUB writer: correctly resolve relative URIs.  (Closes #1671.)
EPUB reader:  Further URI handling improvements.

Now we outsource most of the work to `fetchItem'`.
Also, do not include queries in file extensions.

Improves fix to #1671.

It is possible that this will have some unexpected effects, so
further testing would be good.

Respect indent when parsing Org bullet lists

Fixes issue with top-level bullet list parsing.
Previously we would use `many1 spaceChars` rather than respecting
the list's indent level. We also permitted `*` bullets on unindented
lists, which should unambiguously parse as `header 1`.
Combined, this meant headers at a different indent level were
being unwittingly slurped into preceding bullet lists, as per
Issue #1650.
Escape spaces. Fixes jgm/pandoc#1694.
Fix indent issue for definition lists

Tidy up fix for #1650, #1698 as per comments in #1680.
Fix same issue for definition lists with the same method.
Org reader: fix rules for emphasis recognition

Things like `/hello,/` or `/hi'/` were falsy recognized as emphasised
strings.  This is wrong, as `,` and `'` are forbidden border chars and
may not occur on the inner border of emphasized text.  This patch
enables the reader to matches the reference implementation in that it
reads the above strings as plain text.
Org reader: Drop COMMENT document trees

Document trees under a header starting with the word `COMMENT` are
comment trees and should not be exported.  Those trees are dropped
silently.

This closes #1678.
