Find nice approach for resources text dependant on platform

[prupipho]

To make clear what type of project the user is creating in the Wizard we split the messages.ts into two: - messagesReactNative.ts - messagesWeb.ts.

We are not sure that this is the best approach, we should investigate and think about the best and more maintanable approach for this type of texts.

Ideas:

• different files (messages, messagesReactNative, messagesWeb)
• different resources within the same file (messages.ts has projectName.web / projectName.reactNative)
