Mobile - Creating local database for offline records

[egecans]

We should create a local database for recording user actions in offline mode. We will use Room Database for that, we should also do this code architecture in the scope of MVVM. Therefore, we will create an Entity, DAO (Data Access Object), Repository and ViewModel for all tables we will have.
Sub-issues for that are:

• Mobile - Creating User Table in Local Database #340
• Mobile - Creating Need Table in Local Database #341
• Mobile - Creating Action Table in Local Database #342
• Mobile - Creating Emergency Table in Local Database #343
• Mobile - Creating Event Table in Local Database #344
• Mobile - Creating Resource Table in Local Database #345

I finished Need Table
You can follow my guide: a local database, a Need table, a repository example, a ViewModel example and a dependency Injection example were implemented under this branch. I also added required gradle dependencies

I finished ActionTable according to the Egecan's guide. Now I switched to EventTable.
