unmarked 1.5.1 release

[Ken Kellner]

Hi all,

There's a new unmarked release on CRAN, v1.5.1.

Mostly bugfixes this time:

•     Rewrite colext likelihood in TMB to improve speed and fix missing values bugs
•     Internal refactoring to facilitate long term maintenance
•     Informative error when a user attempts to use nested formula functions such as I(scale())
•     Better generation of random effects for simulated datasets
•     Fix deprecated arma::is_finite warnings from CRAN
•     Remove some deprecated simulate/power analysis functions
•     Other minor bugfixes

There is one change that broke backwards compatability in a few cases. For certain models (such as occuTTD, occuMulti, occuMS), if you saved a fitted model object (i.e. in an Rdata or Rds file) created with the previous unmarked version, that saved object may no longer work properly with some functions such as predict when using the new unmarked version.
