Conservation tracks: give the description pages a real Data Access section, refs #34803

The hgdownload link block on these pages had no header, and on 18 of them it sat
above the Description, which is where it got overlooked. Move it into an
<h2>Data Access</h2> in the usual place, after Methods and before Credits, and
add pointers to the Table Browser, the Data Integrator and the REST API, plus
the maf* and bigWig* command line tools.

134 pages: 55 had a download block that was moved and labeled, 56 get a list
built from hgdownload directories that were checked to exist, 21 have no
download directory of their own and so get the Table Browser and API pointers
only, and 2 already had a Data Access section that was reworked. Existing
download lists are unchanged apart from http -> https and an added
target="_blank".

Wording follows what each track actually holds, so the alignment-only pages do
not claim conservation scores and the Data Integrator is only mentioned where it
can really be used, since it does not handle MAF.

Also corrects one link: hg18 cons44way pointed at multiz44way/maf, which
redirects; it is now multiz44way/maf/.

 <H2>Display Conventions and Configuration</H2>
 <P>
 The track configuration options allow the user to display either
 the vertebrate or placental mammal conservation scores, or both
 simultaneously.
 In full and pack display modes, conservation scores are displayed as a
 <EM>wiggle track</EM> (histogram) in which the height reflects the 
 size of the score. 
 The conservation wiggles can be configured in a variety of ways to 
 highlight different aspects of the displayed information. 
 Click the <A HREF="../goldenPath/help/hgWiggleTrackHelp.html" 
 TARGET=_blank>Graph configuration help</A> link for an explanation 
 of the configuration options.</P>

 The conserved elements were predicted by running phastCons with the
 --most-conserved (== --viterbi) option.  The predicted elements are
 segments of the alignment
 that are likely to have been "generated" by the conserved state of the
 phylo-HMM. Each element is assigned a log-odds score equal to its log
 probability under the conserved model minus its log probability under the
 non-conserved model. The "score" field associated with this track contains
 transformed log-odds scores, taking values between 0 and 1000. (The scores
 are transformed using a monotonic function of the form a * log(x) + b.) The
 raw log odds scores are retained in the "name" field and can be seen on the
 details page or in the browser when the track's display mode is set to
 "pack" or "full".

+<h2>Data Access</h2>
+<p>
+The alignments and the conservation scores can be retrieved for a single region or for a list of
+regions with the <a
+href="hgTables?db=felCat4&amp;hgta_group=compGeno&amp;hgta_track=cons6way">Table Browser</a>,
+which returns the alignments in MAF format and the scores as wiggle data. The scores and the
+conserved elements, though not the alignments, can also be joined with other annotations in the
+<a href="hgIntegrator?db=felCat4">Data Integrator</a>. For automated access, our <a
+href="../goldenPath/help/api.html">REST API</a> serves the alignment and conservation tracks
+individually, by name.

+subset of species, or the alignment underlying a gene, and <tt>bigWigToWig</tt> and
