Improve bad connections handling

[dartvader316]

Description

Adds a button to skip startup connections and go to offline mode to help with Bottles startup on slow and unstable connections.
Adds "Force Offline Mode" setting in preferences/General/Advanced as option to immediately start Bottles on slow and unstable connections.

Fixes #2954 problem for me

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

• sudo wondershaper $NET_INTERFACE 100 100 to limit your connection speed
• run Bottles and test.

Skip button correctly handles skipping 2 stage connection pings and downloading of repositories indexes

Needs a review code-wise from Mirko or another contributor that can. Otherwise, generally LGTM.

I will see if I can test this myself later and land it for the next Bottles release.

Can't test but the code looks good to me

Adds a button to skip startup connections and go to offline mode

Does this only affect Bottles itself (or just startup of Bottles), or does this cut ALL internet traffic, even from all bottles and programs run in them?

The wording of the setting in the preferences ("Force disable any network activity even with available network connection") seems to indicate that ALL traffic is stopped.
