Enable pinning when the ipfs daemon is in offline mode

[rehno-lindeque]

Currently ipfs companion is completely disabled when ipfs is run in offline mode. I.e.

ipfs daemon --offline

However, it should still be possible to pin content when not connected to the network. That is

• This Page > Add to IPFS (Keep Filename)
• This Page > Add to IPFS
• Tools > Open Web UI

Should all be available. Also possibly

• Tools > Share files via IPFS

For this last menu option, the wording "Share" may introduce some confusion. On the other hand, presumably, someone that is savvy enough to run with --offline probably already understands that sharing will only take effect once they put the daemon into online mode.

Thank you for filling this. It compliments #782 nicely, enabling users to add/browse content in truly offline mode.

The fix is to enable Web UI item in browser action menu when peer count is 0.
I believe all is needed to enable offline mode is replace isIpfsOnline (peers > 0) with isApiAvailable (peers >= 0) in two places:

@rehno-lindeque is this something you would be interested in contributing via a PR?
I'd be happy to provide more context if needed.

I'd love to be able to contribute to ipfs related projects but unfortunately I can't justify it for the foreseeable future. Thank you for the suggestion though.

@BrianBelhumeur sweet!
I believe the code did not change much so entry points described in #790 (comment) should be still valid.
