Add a command to visit the homepage of a Bundle

[lucc]

The command BundleVisitHomepage can will try to take the user to the homepage
or directory the bundle is cloned from.

This is not yet system independent and can not yet handle full git uris.

questions and ideas:
This is still work in progress. Do you think it is a feature that should be included into vundle?

It might be interesting for people who demanded some information on the plugins inside the search window where some key could be mapped to this function.

If you have ideas how to handle general git uris or open uris on different systems please comment. (What can you do on windows to open an uri? On linux we might try for xdg-open or are there many window managers and desktop environments that don't support it?)

@lucc Thanks. This is an interesting idea, however at the moment if I understand this right it just opens a local URI with explore? How exactly were you thinking of tying this in? Via the interactive mode as a different button press maybe to open the Readme/doc.txt?

We previously mentioned in #403 that we might want a general means of seeing information on a plugin. I did some research and found this plugin > https://github.com/tyru/open-browser.vim. If this was a dependency, we could open local browser to whatever URI we cared for like the project web page.

@gmarik @jdevera Thoughts?

I like the plugin you mentioned and put it into code. This removes the trouble of writing code to open an url system independent. 👍

If you like it I can add documentation and change the name to suit the new names (Plugin*).

I'm a bit reluctant to take this as it currently is. The feature, I like, but the calling to another plugin, not so much.

First we need to make sure, or a good guess, that the uri is browseable, so we don't try to open a browser for an ssh backed repo. Then for windows, I think we can use simply open and pass the uri, but I'm not sure how it will take the file:// uri, maybe not so well. For linux we can try using xdg-open, wich takes care of http:// and file:// just fine. For mac, well, no idea 😄.

And after all this it still seems a bit brittle.

[lucc]

For Mac it is open :)
I will try to include some original code so that the Plugin is not needed.

Just to be clear, I wasn't meaning to put the open-browser directly into your solution. It would be annoying as a user to have to have a second plugin to make vundle work. I guess I was more posting that as a related thing that might provide information.

[lucc]

I just found #302 to be related.

I rebased this on next and squashed the commits. It should only be merged after v0.10.2.

Just rebased on current master.
