Bump some dev dependencies

[razzeee]

Seems to work fine with Mattermost platform pre release and 3.2

Please rebase and follow my reviews.

You don't have to bump electron-packager. I'm working on updating build commands.
(In addition, gulpfile.js uses the deprecated parameter, version-string. So this might break artifacts.)

[yuya-oc]

If you write the detail, for example, the motivation to bump, the part which you checked, etc., it's helpful to review.

[yuya-oc]

As you wrote, electron 1.4.0 seems to work with the pre-release server and v3.2.0 server. So I think we can bump electron.

welcome back @razzeee :)

Thanks!

@razzeee Just curious, post's background blinks when moving the mouse cursor across the posts. Have you experienced?

[razzeee]

@yuya-oc
They just highlight, as normal for me on windows 10

[yuya-oc]

Tested again on Window 10 and macOS.

On Windows 10, I saw the blinking like the gif (actually, it's very fast blinking). @jasonblais and others, would you check this?

On macOS, the app seems to work well.

@yuya-oc

Hmm, haven't been able to reproduce the blinking. I tried it on the very same messages you shared above. Does it reproduce consistently across channels and messages?

[yuya-oc]

@jasonblais Yes, it happens also on channel list, but messages cause that more often. It seems that the vertical position of mouse cursor is randomly wrong in the window, so I see the blinking.

Then, I tried the app on some DPI. On 100% and 125%, the problem seems not to happen. On 150%(I'm using), it happens. I think almost of users use 100% or 125%, so I feel we might as well merge this for now. Any thoughts?

[jasonblais]

Yeah, I think merging makes sense.

Should we add a known issue for the next changelog that using DPI of 150% might cause the vertical position of mouse cursor to be incorrect? It's okay not to fix it, but let's others know about it.

[yuya-oc]

@jasonblais Sure, that should be written. I add it later.
