Add mobile flag to also generate mobile friendly files

[ZXY101]

Description

Add a new mobile flag, when true it will generate additional mobile optimized files:
.mobile.html, styles.mobile.css and script.mobile.js (given that as_one_file is false).

The default functionality should be exactly the same, as for the mobile files:

• Removed panzoom and related functionality
• Make the background black and add simple navigation buttons to the bottom of the screen
• Add in in swipe-to-navigate functionality

Panzooms bounds options does not seem to work correctly so there doesn't seem to be a way to not navigate off screen into the void which is quite annoying. So I've removed panzoom and just handle resizing the page to the screen. For panning and zooming the browser should handle that by default, I've just added some additional touch event logic to be able to change pages via swiping.

Usage

$> mokuro "my-manga-01" --mobile True --disable_confirmation True
'// _ocr, my-manga-01.html, my-manga-01.mobile.html'

$> mokuro "my-manga-01" --mobile True --disable_confirmation True --as_one_file False
'// _ocr, my-manga-01.html, script.js, styles.css, panzoom.min.js'
'// my-manga-01.mobile.html, script.mobile.js, styles.mobile.css'

I've mainly done this for my own usage, I can't confirm if this works as expected on other devices especially IOS.
I tried to make sure I didn't effect the default experience in any way, can still be improved some but it's at a point where I can comfortably use without issue.

Hey @kha-white, any chance you could look at this?

Is this project still being maintained?
