Fixed Makefile PHONY line.
Relaxed old-time version bound, allowing 1.0.*.

I see no reason for the restriction, which requires a recent
Haskell Platform.

The module is only used in make-pandoc-man-pages anyway.
make-pandoc-man-pages:  CPP macros to import right time module.
.gitmodule:  Use https rather than git URL.

iThis helps people behind firewalls.
Increased ansi-terminal upper bound.
Parsing: Much faster new version of anyLine.

Not only faster but uses less memory.
Markdown reader:  More efficient version of scanForPipe.
Makefile: Don't enable tests in 'make prof'.
anyLine:  Set position properly.
More anyLine tweaks: Use incSourceLine.
Parsing: More improvements of anyLine parser.
Use anyLine everywhere instead of 'manyTill anyChar newline'.
Markdown reader: Performance improvement in str parser.

Moved a guardEnabled out of an inner loop.
Markdown reader: Moved guardEnabled to definitionList.

From definitionListItem.
Slight performance improvement.
Minor code cleanup.
Changed copyright date range on Markdown reader.
RST reader:  Allow anonymous form of explicit links.

`hello <url>`__
Closes #724.
Markdown reader:  Simplified and sped up str parser.

We no longer needed the smart quote complexity, because of
improvements to singleQuoteStart and singleQuoteEnd.

And we were able to move the check for intraword underscore
to the emphasis parser.
Removed hsmarkdown.
Markdown writer:  Use autolink when link text matches url.

Previously we also checked for a null title, but this
test fails for links produced by citeproc-hs in bibliographies.

So, if the link has a title, it will be lost on conversion
to an autolink, but that seems okay.
