Feat/proxy setting

[yosheng]

I need Caprine could proxy by setting without system proxy setting, so I add proxy setting in Advance Setting menu

When I click proxy setting it will open a windows and show default setting.

After click Enable and enter proxy server and relaunch caprine. Enjoy it 😎

I will be glad, this PR coluld help to your project too. 🥰

@yosheng Two things I noticed, first, you have a redundant trailing </div> at the end under </script>

Second, this should be made into a regular .html file and put in //static, then loaded with a line like:
win.loadFile(path.join(__dirname, '..', 'static/proxy.html'));

See my commit where I fixed all this (as well as migrated my own preload script to typescript, and renamed yours to proxy-preload.ts), as well as added a few styling changes to the window that I think look good > Alex313031@3742bbf

@Alex313031 I appreciate about your propose! I'am a electron newbee, those suggestions will help me to know how could make code clean. 🤩
I will do some change, then reopen this PR.

I added some blue color like this.

@yosheng Looks good, I will include your styling in my fork.

Also, you indented your .html better, I will do that too lol.

Also, in case you were wondering, the Roboto font is to match up with the rest of Electron. Electron uses Roboto by default, and most of the Caprine UI is in that font.

Also, proxyWin.setMenuBarVisibility(false); is not needed since you already have autoHideMenuBar: true,.

@Alex313031 Thanks for your advice! 😎
