The main goal of this commit is to change the way we load the files containing deprecated functions. This files are located into the `src/bp-core/deprecated/` directory and there's one file for each version of BuddyPress we created to store the deprecate functions.
We noticed that these files were not necessarily loaded although they should have. This case happens to all users who firstly installed BuddyPress when its version was upper than 2.7.
>From now on, here's how deprecated code will eventually load into your BuddyPress installation:
- First installs won't load deprecated code.
- Updated installs will load the **2 latest BuddyPress versions deprecated code**.
- Defining the `BP_IGNORE_DEPRECATED` constant to `true` will change the 2 above points behavior ignoring any BuddyPress versions deprecated code.
- Defining the `BP_IGNORE_DEPRECATED` constant to `false` will change the 2 first points behavior loading **all** BuddyPress versions deprecated code.
Props djpaul, dcavins.
