This function is similar to Linux's list_for_each_safe(), and lets you
iterate over a database even if the current item is removed.

I also take the chance to modify this function slightly. Now, if a
matching item could not be found a new item will be allocated.
I added the new function db_get() if callers just want to get an item
without allocating.

I also introduced a file_readf() function to make it easier to read a
formatted string from the file.

I replace it with calls to g_strdup_printf(). This has the additional
benefit that I can do uint conversions at the same time as other
formatting options, so this seems like a win. The only downside is that
I have to manually free the memory that glib allocates, but that's easy
enough.

This function converts unsigned ints into strings. This allows me to
replace several almost identical functions with one function call.

I move the code into a new cpp file, so it is no longer a header-only
library. I also take the chance to add a for-each function for testing
iterators.

This variable should only be set by the Database when a DatabaseItem is
first created. This means I should hide _index from the rest of the
world to prevent accidental modifications. I also add an accessor
function for other code that needs to read _index.

I move all of the core tests into the core/ directory to keep them
together. Gui unit tests will be put in new directories.
