lme4 1.1-19 going to CRAN soon

This is a heads-up that we'll be sending a new version of lme4 to CRAN
soon.  This is not a major revision (the proximal reason for sending a
new version is to address some minor CRAN-compatibility issues).
However, I did *almost* make a "brown paper bag release"
<http://www.catb.org/jargon/html/B/brown-paper-bag-bug.html>, so if
anyone feels like taking the development version for a spin in the next
day or so that would be appreciated.  (The new version is due on CRAN by
Nov 9; we have otherwise completed testing on Travis, win-builder,
reverse dependencies, etc ...)

  cheers

=====
  NEW FEATURES:

         ? influence measure code from ?car? rolled in (see
           ??influence.merMod?)

         ? ?mkReTrm? gets new arguments ?reorder.terms?, ?reorder.vars?
           to control arrangement of RE terms and individual effects
           with RE terms within model structures

         ? adding material from the ?RePsychLing? package (on GitHub;
           see Bates et al 2015 arXiv:1506.04967) to show orthogonal
           variance components.

  USER-VISIBLE CHANGES:

         ? ?as.data.frame.merMod? finds conditional variance
           information stored either as ?attr(.,"postVar")? or
           ?attr(.,"condVar")? (for ?glmmTMB? compatibility)

         ? change to defaults of ?[g]lmerControl? to print a message
           when fits are singular

         ? new utility ?isSingular()? function for detecting singular
           fits; by default a message is printed for singular fits

         ? ?allFit? function/methods have been moved to the main
           package, rather than being included in an auxiliary source
           file

         ? post-fitting convergence checks based on estimated gradient
           and Hessian (see ?troubleshooting?) are no longer performed
           for (nearly-)singular fits (see ?isSingular?)
