Minor clean up on the downloads page (#444)

* Add "Accumulo" before the raw version numbers, to distinguish from
  other libraries/subprojects also listed on the page
* Clarify use of "Latest" and "Legacy" badges to indicate current and
  previous generation of LTM releases when they overlap
* Use unique anchors for specific sections of the page
* Drop the links to the 1.10 LTM version whose maintenance window has
  elapsed (will archive the corresponding artifacts in SVN)
