Ran examples and fixed any imediate problems I could.  These fixes include:

1. @examples p_opendir p_opendir("~") to p_opendir(path.expand("~"))

2. The p_update didn't do anything for update=FALSE.  I used old.packages to return a list.  Also added `ask = FALSE` and ldots as arguments to this function.

3. Updated utils.r's left.just to be more flexible (the newest qdap version allows specific columns)

4. Added a print class to search_any to left justify the text

5. p_unload unloaded pacman in the examples and then used the function more but there was not pacman.  So I use library(pacman) in the examples.

Still to fix:

1. p_citation()     ## bug in the clipboard copy
2. p_interactive()  ## not loading
