Update packages and many small fixes

[DeionSi]

This pull request does multiple things. It was not feasible for me to develop them separately from each other as they are intertwined in many cases.

• Update all packages to latest version. Remove json5 dependency. Replace serialport with the sub-dependancy of @serialport/bindings-cpp. Remove deprecated request package and replace with native fetch. A lot of small changes as a result electron upgrade.
• Use NPM jQuery instead of included.
• Improve styling of selects
• Imrpove top bar handling (including hiding firmware details which couldn't be clicked on)
• Re-enable scrolling between the different pages. Changed all button handling to trigger this scrolling.
• General improved layouts of the different pages.
• Made base tune warning message into a separate page instead of a separate window.
• Fix opening ini folder on Windows

Details are in the commits. All functions are working for me with a mega ECU.

Closes #33, #32. #31, #29, #28, #25, #24, #20, #16

Looks good and tests out fine! Great work with those dependencies as some of them are a huge mess.

There's a couple of very small layout things I'm not convinced about (The warnings screen change for example) but nothing major and all just stylistic choices.
