Add bundleIdPrefix

[yonaskolb]

Fixes #62
This is used for automatically generating PRODUCT_BUNDLE_IDENTIFIER if it's not specified

[yonaskolb]

I just realized this could be solved without this feature

bundleIdPrefix: com.company

vs

settings: 
  PRODUCT_BUNDLE_IDENTIFIER: com.company.$(PRODUCT_NAME)

Is this feature, worth it then? Maybe not

@yonaskolb, I think it worth, I mean it. This is something I wanted, too.
I'm currently using variables to achieve this like below:

projectName: &projectName ProjectName
bundleIdentifier: &bundleIdentifier jp.co.ClientName.ProjectName

name: *projectName
targets:
  *projectName:
    settings:
      base:
        PRODUCT_BUNDLE_IDENTIFIER: *bundleIdentifier

I always wanted to do something like this: *bundleIdentifier.*projectName but yaml doesn't seem to be able to do it.

bundleIdPrefix: com.company

This would be some 'unique' nice feature of XcodeGen. More clearer when you look at it.

@kixswift thanks for the feedback. You don't think this is simple enough?

settings: 
  PRODUCT_BUNDLE_IDENTIFIER: com.company.$(PRODUCT_NAME)
targets:
  MyTarget:
    platform: iOS
    type: application
  MyFramework:
    platform: iOS
    type: framework

MyApplication would get a PRODUCT_BUNDLE_IDENTIFIER of com.company.MyTarget and MyFramework would get com.company.MyFramework

Also maybe this should be moved to project.options like carthageBuildPath

Um... well, actually you have a point and this might be just my personal preference. And I totally agree with you that this is an option.

Are there any other reasons why a bundleIdPrefix would be useful? Xcode makes you set one when creating a project and calls it the Organisation Identifier, but I don't think they use it for anything else then to prepend to bundle ids

I like the idea of using the bundleID prefix. Having the prefix as an option will ensure that all the bundle identifiers are consistent across the targets.

@pepibumur, that's good point 🎉
