[Feature]: show plugins option (--verbose?) to show plugin source URI/http uri - as there is no plugin documentation.

[metimocyn]

Expected behavior

$ bash-it show plugins --verbose

Plugin               Enabled?   Description              Reference
alias-completion     [ ]                                 https://github.com/Bash-it/bash-it/blob/master/completion/available/aliases.completion.bash
autojump             [ ]        Autojump                 https://github.com/wting/autojump
aws                  [ ]        AWS helper functions     https://github.com/Bash-it/bash-it/blob/master/plugins/available/aws.plugin.bash
base                 [x]        miscellaneous tools      https://github.com/Bash-it/bash-it/blob/master/plugins/available/base.plugin.bash
....

or something like:

$ bash-it show plugins --verbose

Plugin               Enabled?   Description              
alias-completion     [ ]
                                  https://github.com/Bash-it/bash-it/blob/master/completion/available
autojump             [ ]        Autojump
                                  https://github.com/wting/autojump
aws                  [ ]        AWS helper functions
                                  https://github.com/Bash-it/bash-it/blob/master/plugins/available/aws.plugin.bash
base                 [x]        miscellaneous tools
                                  https://github.com/Bash-it/bash-it/blob/master/plugins/available/base.plugin.bash
....

Current behavior

$ bash-it show plugins

Plugin               Enabled?   Description
alias-completion     [ ]        
autojump             [ ]        Autojump configuration, see https://github.com/wting/autojump for more details
aws                  [ ]        AWS helper functions
base                 [x]        miscellaneous tools
....

Possible solution

add a reference/doc variable to each plugin so that users can look into the details of the plugin and what it does.
