refactor local versionName

- with a leading 'v' in versionName (e.g. v0.9.8-96-g082c2c5 master)
it is not possible to execute uploadwebtests and upload projects to
pocketcode.org with a local build.
- updated projectVersion to be consistent for jenkins and local builds
- lintOptions abortOnError has to be set to false - otherwise
our jenkins build would always fail in case of lint errors;
the run should go on and only report the errors
