fix(seed): CRSF and token issues

[daraosn]

When express.static() is serving index.html it breaks the middleware chain and avoids the CRSF to be set on / request, causing the first login to fail, whenever users have no cookies set.

I think this relates and possibly fixes #2224, #2511, #2611 and krakenjs/lusca#95

This commit basically renames _index.html to app.template.html which is more expressive, and the generated file will be app.html which avoids express.static() blocking the middleware chain, because there is no index.html anymore. Therefore routes.js:sendFile is effectively called.

Note that I tried and played around A LOT with webpack trying to find another solution, this was the most elegant one I could find.

Great work!

@Awk34 glad to contribute and thanks for such a nice framework!

@Awk34 @daraosn What is the best way to solve this issue for code which was built from the seed before this fix? Will the renaming of _index.html to app.template.html and changes in gulpfile.babel.js, routes.js and webpack.make.js fix this?

[Awk34]

I certainly hope so

[daraosn]

@yeaske yes, that's pretty much what needs to be done, please double check here: https://github.com/angular-fullstack/generator-angular-fullstack/pull/2613/files
