Fixed bugs in dynamic phenology code - based on Yun Yang and Elizabeth Garcia's testing
Include phenology fixes
Merge branch 'master' of https://github.com/RHESSys/RHESSys
Changed "return(0);" to "return;" (the former being invalid C) to
allow RHESSys to be compiled using the default clang front-end used on
newer versions of OS X.  (Note that return is not required for
void functions.)
Updated function definitions so that each function is a void function,
which reflects their declarations and actual implementation.  Non-void
functions that lack a return value will not compile under the
clang front-end that ships with the latest version of the XCode
command line tools under OS X 10.8 and 10.9 (and maybe 10.7 too).
Updated function definition to reflect void nature of function.
Merge branch 'master' into develop
