Add ‘sourceforge’ and ‘bitbucket’ as search terms

I have a lot of bookmarks to projects hosted on those sites.
Add argument that will show a count of the bookmarks

For the sake of curiosity I am sometimes interested in how many
bookmarks I have for a given subject.  This patch adds two
command-line arguments, ‘-c’ and ‘--count’, which will print the total
number of bookmarks at the end of the output.
Add search terms ‘emacs’ and ‘vim’
Bump the version to 2.1.0 over the new ‘--count’ argument
