[PATCH v3] gitk: tag add right click options

["ZheNing Hu via GitGitGadget" <gitgitgadget@gmail.com>]

From: ZheNing Hu <adlternative@gmail.com>

In gitk, we can right-click on the icon of the branch,
and a directory will pop up to provide us with functions
such as "Checkout this branch", "Rename this branch"...,
but we found that the right-click tag icon does not have such
a function , So I learned how to write the branch icon, and
added the following functions "Rename this tag","Remove this tag",
"Copy tag name" to right-click the tag icon. This function is
temporarily supported work on the branch with <=3 tags.

    gitk: tag add right click options
    
    This patch want to fix: https://github.com/gitgitgadget/git/issues/855
    
    We can provide for right-clicking the tag icon in gitk Rename this tag",
    "Remove this tag", "Copy tag name" function.
    
    For convenience, only the tags on the branch with the number of tags <=3
    are processed temporarily.
    
    Thanks!
