[Feature] Add importing Swithy proxy list

[zzzgit]

Hi, I am from Swithy.

I am using smartProxy now. The only problem for me is importing the Swithy proxy list. Currently, there's only importing support for Autoproxy.

Current Status

1. Import Rule (with AutoProxy file) doesn't work functionally. The parsed rules object couldn't be de-serialized to ProxyRule class.
2. Subscribe rule list to SwitchOmega: it ignores "!" mark (means DIRECT) , which have the opposite effect.
3. Some SwitchyOmega condition cause parsing error: it requires U2 (uglify ast) to compile which we are not bundled. So these conditions should be filtered out. (For example FalseCondition (Disableld) , BypassCondition etc ... )

Design:

• We could unify some functions of the Import rule with file and Subscribe rule list .

  • Use same parser for one format , but different converter to ProxyRule or SubscriptionProxyRule

• SwitchyOmega has 2 formats of exported file (and 1 format of backup file)

  • transitional: without "@with result" mark ,
    • we should handle "!" correctly
    • we should show a window asking user all these rulse should use which proxy ( default/active/ or others)
  • modern: with "@with result" mark ,
    • we should handle "+direct" correctly
    • we should either give up all the proxy servers and show a window asking user all these rulse should use which proxy ( default/active/ or others)
    • OR we should gather all proxy servers in the file and show a window let user define the mapping between original proxies in file to proxies (default/active/or others) in smartproxy .
    • backup files:
      • we might also support import profiles

I'm working on the Import Rules window atm.
It will use the externalAppRuleParser.Switchy.parseAndCompile and externalAppRuleParser.Switchy.convertToSmartProxy provided by RuleImporterSwitchy.js I will not touch RuleImporterSwitchy.js though

With this change both Rules Subscription and Rule Import will use only one method to do the parsing and importing.
So yeah the unification is happening

BTW any backup of Switchy rules would help a lot, I don't any atm.

As for SwitchyOmega formats, I have imported the parser directly from the Switchy extension. So if that is not working as intended is a surprise to me! That is found in here: RuleImporterSwitchy.js

Where I really need help is to fix the parser if there is any issues. I have very little free time and can't go through specs and the existing parser to iron out the bugs.

So if you want to work on this please hold off until I finish the work on Import Rules popup and its back-end. When that is finished I would appreciate your help fixing the parser itself.

To track the further work on SwitchyOmega rules I've created #345

This option is added the popup.
@jackyzy823 the backend work of the importer is sorta finished but there seems to be bugs in the switchy rules parser. Feel free to jump in the code :)
