Add shortcut

[simepy]

Hello,

This pull request answer to issue #5

I add the shortcut "ALT+q"
When you press shortcut this open iframe below the word or above if iframe have no enough space
I thing make option panel for shortcut in a future version, but I don't understand how it work, at the moment

PS: this is my first pull request, if I do something wrong, just tell me :)

Sorry for the delay.

This patch works great :-)

Thanks to move URLs to HTTPS. I hope this can fix some other reported issues.

I just have some questions about...

... UX:

• Why Alt+Q?
• Why do'nt use borders nor shadow to separate the translation box from website?

... structure:

• What is your intention when declaring web_accessible_resources?
• Do you have an idea in how to not repeat the pairUrl variable into popup/script.js and popup/contentScript.js?
• Do you have any reason to keep all files into popup/ folder? (ie.: popup/contentScript.js instead of content-scripts/script.js, and popup/background.js instead of background.js)?

Note: I forget to put .editorconfig file, it was my fault, I'll handle it after

Hello,

Thanks :)

UX:

• I had selected Alt+Q completely random... but also because this key is easy to touch but if want to change go ahead :)

• Yes this is a good idea, but the border is printed before the content this is not good... and I don't know how print the content and if the content is loaded add border

Structure:

• I add this for export frame.html and add to web page, but It work well without, I remove it
• Unfortunately not, I search how to fix this but I don't find a solution at the moment
• No, this is a good idea, I make it

Thanks for your time
