EnsureNodeFiles not robust enough

[cmxl]

I use the WebOptimizer.LESS and WebOptimizer.Typescript packages with the latest beta build.

Following folders will be populated with the node_packages:
%TEMP%\WebOptimizer.Node\LESS\
%TEMP%\WebOptimizer.Node\TypeScript\

As long as the folders did not exist before, everything works fine.
But somehow the initial files %TEMP%\WebOptimizer.Node\LESS\index.js and %TEMP%\WebOptimizer.Node\TypeScript\typescript.js were gone on my PC (maybe my antivirus software removed them).

The next runs never recreated those files because it is only ensured, that the certain folder exists, but never the needed files. Maybe EnsureNodeFiles needs to be abstract to check for those files in the concrete implementations.

PS.: I don't know if I should post this issue in the other repos, because it is somehow referred to the
EnsureNodeFiles function of the NodeProcessor.

This is a very old issue, but wanted to revive it, because it still is an issue on some systems where I use WebOptimizer.

Changing the base class would also mean to update all the dependent packages to properly handle EnsureNodeFiles.

I don't know if this is practical, but I'd like to help out.

Any thoughts @madskristensen?
