Swift 4 Support

[vknabel]

Thank you very much for your great project!
Currently SDE doesn't work for Swift 4 projects as stated in #38.

Some dependencies have released updates, which broke the current master branch. I bumped the vscode engine dependency to ^1.16.0 as it is required by the language client (see microsoft/vscode-languageserver-node#248).
As a bonus, the implicit typescript update allowed me to remove a fixme and use generics.

Swift 4 probably renamed Swift 3.1's modules property to targets, when running swift package describe --type json (credits to @ainopara). Now SDE will simply fallback to targets, temporarily eliminating the crash. In the long run, there should be a better error message (e.g. "Swift version not supported.").

After all I haven't tested a lot (e.g. regression errors at runtime through dependency upgrades), but the basic functionality is now restored for Swift 4 on Macs (I'm not sure about Linux support though).

For the ones of you, who trust me and really need Swift 4 support as soon as possible, I uploaded the current vscode extension. If you need help for installing it, here is the the official installation guide.

Thanks! Have been waiting patiently for Swift 4.0 support, will test the patch and hopefully it will be merged into mainline soon.

@vknabel thanks for PR...
@dcartman and thanks for your watching...

But, as you seen, this project stopped for a while... Do you have interest to fork a new project? I'am glad to pin your new fork at the top of this project.

[vknabel]

@jinmingjian I respect your decision and have to thank you very much for this project. Yes I am interested in maintaining SDE, although it may take a while to fully understand linux support.

An open question: shall I publish further updates as a new vscode Extension?

[jinmingjian]

@vknabel yes, because one extension is usually published by the individual developer on behave of his own account.

for me this update works, but when I'm using autocomplete I got two '.'
ex: self..engine..createCommandPool()

[vknabel]

@jinmingjian could you add a link to the fork? vknabel/vscode-swift-development-environment

@jinmingjian Is there no way to transfer ownership of the extension inside of VisualStudio Code? So that us users can get upgraded automatically? I would really appreciate it!
