WIP : Fix for OSS issues and a couple of bug fixes

[dan-dr]

• Add custom setting codeCliPath for OSS users
• Add usage of the documented useCliBaseInstallation
• Fix removing and adding extensions without cli to use lowercase pacakage names

Short description of what this resolves:

Fixes issue where the extensions didn't sync under the OSS variant of VS Code.
The problem seemed to stem from the inability of the extension to find the cli of VS Code.

Changes proposed in this pull request:

• Let users set the cli path of VS Code in the extension local settings
• Let users disable installation using the useCliBaseInstallation settings - which was documented but not used anywhere - which also fixes OSS issues (depending on the next listed change)
• Force installation and deletion of extensions without cli to use lowercase folder paths for the extension paths, otherwise VS Code might not recognize the extension is installed, or the extension my not be removed if installed manually.

Fixes: #668

How Has This Been Tested?

Ran this on my local dev machine (Solus Linux) where downloading and removing extensions didn't work at all using the OSS variant of VS Code.

Performed multiple installs, uninstalls, uploading and downloading of settings.
Without manually editing the new custom settings, the extension behaves exactly the same, so users who do not have issues will continue normally.

Checklist:

• I have read the contribution guidelines.
• My change requires a change to the documentation and Github Wiki.
• I have updated the documentation and Wiki accordingly.
• Test with existing Non OSS versions.

As you have tested this in your machine with OSS version of code.

Can you test it also for Standard, and portable version for NON OSS code so we make sure it doesnt break on the existing versions of code?

[dan-dr]

Sure. I'll try to test those on Windows soon. If someone else wants to chip that'll help.

[tristan957]

@dan-dr have you tested on Windows yet?

[knobhead]

this surely would be a nice christmas present :-) 🎄

[shanalikhan]

Yes, I will release new version. Once its been tested for Non OSS versions of code ( to make sure it doesnt break existing) also like tested for OSS versions.

What is the status of this?

Soo.. Abandoned? :/
