Fix warnings

[Rumperuu]

• Provide temporary fixes for issues ‘register.component.ts depends on 'ng2-validation-manager'. CommonJS or AMD dependencies can cause optimization bailouts.’ #117 and ‘ng2-charts.js depends on 'chart.js'. CommonJS or AMD dependencies can cause optimization bailouts.’ #119
• Close ‘environment.dev.ts is part of the TypeScript compilation but it's unused. Add only entry points to the 'files' or 'include' properties in your tsconfig.’ #120
• Updates @angular/cli, @angular/core and rxjs
• Should close ‘fixed 249 of 261 vulnerabilities in 1909 scanned packages — 12 vulnerabilities required manual review and could not be updated’ #116 if I can figure out how to sort it
