Mockoon 1.17.0 + Portable

UI redesign:
To improve some features' discoverability and declutter the interface a bit, we redesigned the main header. We also polished the interface a bit here and there.
Here are the most significant changes:
New header design:
We transformed the main header into a new menu with tabs to make the proxy mode and logs more easily discoverable. We also split the environment settings into three new sections: the environment headers, the proxy options, and the environment settings.
The environment's information previously available in the header are now in the "Settings" tab.
Environment's menu improvements:
We made small adjustments to the environment menu:
You can edit the environment's name directly in the menu.
We removed the "CORS" icon as the option is always enabled and moved the "HTTPS" icon next to the URL.
The "Truncate long paths" option in the application settings (ctrl+comma) also applies now to the environment menu. If enabled, environment URLs won't be truncated anymore.
new-api:
Headers and rules "click-to-confirm" delete button
Headers and rules lists now uses a click-to-confirm delete button:
Responses list improvements:
The route responses menu is now split into two lines as it was becoming too cluttered.
File and body information display improvements:
We reorganized the "Status & body" tab. More precisely, we removed the redundant Content-Type information and replaced it with a small "footer" under the body editor. This footer will always display the effective Content-Type taking the order of precedence into account:
environment headers ? file mime type ? route headers
Ability to provide custom TLS certificate:
You can now provide a custom TLS certificate to serve your mocks over HTTPS. Mockoon still uses the same self-signed certificate as before if you don't provide a custom one.
New response rules for cookies:
A new response rule is available to check a cookie's value or presence:
New templating helpers:
New Handlebar helpers are available: join, len, gt, lt, gte, lte, eq, toFixed, round, stringify, slice. Head over to the helpers documentation to learn how to use them.
Misc:
When creating a new environment, the default name won't be "New environment" anymore but will be taken from the chosen environment's file name.
Cookie domains are now removed when forwarded with the proxy mode.
Bug fixes:
Fixed setVar helper which could not handle Object, 0 or Arrays.
Fixed switch/case helpers which wouldn't work properly with number.
We switched from using a (heavy) icons font to using inline SVG to solve the icons flickering issue when loading the application.
