Added if_found to subdir

Added a new keyword argument to the subdir command. It is given a list of dependency objects and the function will only recurse in the subdirectory if they are all found. Typical usage goes like this.

d1 = dependency('foo') # This is found
d2 = dependency('bar') # This is not found

subdir('somedir', if_found : [d1, d2])

In this case the subdirectory would not be entered since d2 could not be found.
