title: How to reset VSCode Typescript Version
body: <p>I have been working on a typescript project with Visual Studio Code.  We are using an older version of typescript (1.8.10).  This has been no problem up until now, because I have the correct ts compiler package installed locally, and  I could simply click on the status bar in vscode to set the typescript version back to 1.8.10.</p>
  
  <p>However, this morning, I accidentally used a 2.x keyword, and VSCode automatically bumped itself to 2.8.  I realized what I did, and undid the code change.  </p>
  
  <p>My problem is that now that I have done that, VS Code won't let me go back to 1.8!  When I click on the typescript version in the status bar, only v2.8.3 is offered, and manually typing 1.8.10 has no effect.</p>
  
  <p>There must be some sort of config somewhere that is preventing me, but I can't find it.  I checked my package.json file, and confirmed that we still specify the 1.8.10 compiler in the devDependencies section.  </p>
  
  <p>I get that I will still be compiling 1.8, but the tools/syntax guide in vscode are now following 2.8.  What can I do to correct this?</p>
