Adding support for TabBar with Gotags

[ceocoder]

@fatih - Thank you for the plugin, I added support for TagBar after reading this

[fatih]

Thats a tagbar related thing. Can you remove this section completely? I'm going to include a gif with some predefined screenshots and they all need to be consistent :)

[ceocoder]

removed.

[fatih]

Thanks, I've had a plan to add a feature for that, see #59. Let's see what we can do here.

[fatih]

That's a wrong approach. Look at gosnippet.vim where I've checking for the plugin itself and then defining the settings.

[ceocoder]

fixed - added to plugins/ and added check if the plugin was installed. Thank you.

[fatih]

Btw I have a plan to include this, if you can wait a little I'm going to implement this asap.

There are several problems with this pull request:

• You need to check for plugin/tagbar.vim not plugin/tagbar
• You only can return from a function. You need to call finish if you use a simple if clause. This works for me:

if globpath(&rtp, 'plugin/tagbar.vim') == ""
    finish
endif

• Tagbar doesn't work if there is no ctags installed: ctags are required if per-language confuguration specifies another binary preservim/tagbar#94
