feat(app): update openui5-bower version to 1.18.8
feat(Components): Handle component namespaces

- prompt if the user want's to add the application namespace to the object path or not
- if not, the generator tries to add the path to the object root in the bootstarp or as a local resource
- if yes, the gnerator adds the application path (read from the index.html bootsrap - first object root) and suggest it as application path. The user has the possibility to change that if needed.

fixes #47 #2
Merge branch 'feature/namespaceSupport' into develop
fix(file rewrite): fix file re-write capability.

- Fix formatting for html template files to be all tabs for whitespace (some spaces had crept in) which stuffs up the formatting of file rewriting.

- Added an args option to the rewrite() function to specify extra indents.
