wally package missing dependency on libqt4-sql-sqlite

[Steve E]

After installing wally in a Trusty-based release, the basic functionality worked, but the History feature would just display a blank box. To debug it, I ran `wally -debug`. This generates output on the command line to help debug. In that output, I found ...

       Application::Application() db connection failed

I downloaded the source files and added another debug message to print out db.lastError(). This indicated that the db
connection failed because "QSQLITE driver not loaded".

The history feature of wally requires access to a Sqlite database. That only works if .../qt4/plugins/sqldrivers/libqsqlite.so is installed, so libqt4-sql-sqlite should be listed as a dependency in the package.

After I installed the libqt4-sql-sqlite package, wally history started working. Please add that dependency to the package so that wally history will work for all users.
