Add Ctrl-Shift-C shortcut

[cwharvey]

Copies address at cursor from hexdump, graph and disassembly views

I don't really know Qt, so double check the new QShortcut usage

Test plan

Copied addresses from hex, graph and disassem views with both menu and shortcut

Closing issues

Fix #1474

[ITAYC0HEN]

Thank you for you quick improvement with adding support for hex! :)

Next time, you don't have to close the previous PR, you can simply push changes to your branch, and it would immediately take place in the PR :)

For example, you could simply push your changes to "TheLorax:copy-address-shortcut"

Please make Copy Address in the context menu (graph and disas), separated by a separator. And under "Copy" when available. As you can see in the image below, there is a separator under "Copy" and after it there is the "Copy Address". It makes more sense to pair them together to the same section of the context menu

Other than that, looks very good :)

I don't normally use github, how do you update a pull request? Amend and force push? 2nd commit (ugly)?

[ITAYC0HEN]

You simply need to push the changes from your local branch to the remote branch

$ cd cutter
$ git checkout hexdump-improvements
<do changes>
<commit changes>
$ git push 

Usually, what I do, from scratch is:

$ git clone https://github.com/radareorg/cutter
$ git remote add TheLorax https://github.com/TheLorax/cutter
$ git checkout -b my_new_branch
< do changes >
< commit changes >
$ git push TheLorax

Now you can go to https://github.com/TheLorax/cutter and make a pull request

If you want to add another commit to the PR, simply push again to your branch and the PR will be updated automatically:

< do changes >
< commit changes >
$ git push TheLorax

Just a reminder that new member pointer syntax for connecting signals and slots has been available for a while. connect(foo, &Foo::signalname, bar, &Bar::slotname). It has benefit of being checked at compile time. It's easy to silently break SIGNAL and SLOTS macros while refactoring.

@TheLorax can you please improve this Connect method as recommended by @karliss?
