makepipe 0.2.2

• Added a build argument to make_* family to allow a Pipeline to be built without being executed. Once the pipeline has been fully 'registered' it can be built via

p <- get_pipeline()
p$build()

• Added a touch() method to Pipeline which updates the file modification times of all targets to the current time. This is useful when you know your targets are all up-to-date but makepipe doesn't, for example after a negligible change was made to your source code. The new build argument described above comes in handy here: setting build=FALSE you can construct the make 'graph' without executing it, then call

p <- get_pipeline()
p$touch()

This will update the times for all the targets in the pipeline so that when you call p$build() nothing will happen (unless one of your targets is set to force=TRUE).

• Upgraded the internal webshot dependency to webshot2, which doesn't depend on the unmaintained PhantomJS.
