Feedback to improve compileOnSave with tsserver.

I have implemented inside Eclipse compile on save with tsserver by consuming compileOnSaveAffectedFileList and compileOnSaveEmitFile commands. It works great but I think we could again improved it

For compileOnSaveAffectedFileList:

• compileOnSaveAffectedFileList should throw error when the given file is excluded of tsconfig.json. It will give the capability to display an error dialog when user wishes to compile a ts file which is excluded by tsconfig.json
• in some case, tsserver compileOnSaveAffectedFileList returns *.d.ts files (see ttps://github.com/angelozerr/typescript.java/issues/190#issuecomment-317876026) those *.d.ts files must be ignored for compilation.

For compileOnSaveEmitFile:

• the reponse compileOnSaveEmitFile should return diagnostics errors. I had to call the two tsserver commands syntacticDiagnosticsSync and semantacticDiagnosticsSync after the call of compileOnSaveEmitFile to display errors in the Eclipse "Problem View"
• the reponse compileOnSaveEmitFile should return the emited files path (js and *.js.map). In Eclipse case it's very helpful because I could refresh the files.

Commencez par les points d’entrée de tsserver pour compileOnSaveAffectedFileList et compileOnSaveEmitFile, puis examinez les commandes associées syntacticDiagnosticsSync et semantacticDiagnosticsSync. Le travail est terminé lorsque les fichiers exclus produisent une erreur, que les fichiers de déclaration sont ignorés et que compileOnSaveEmitFile signale les diagnostics ainsi que les chemins des fichiers JavaScript et source-map générés.
