Added the bar for search and filtering. It doesn't do anything right now and will be removed from other fragments shortly.
Added filter fragment drawer to the right hand side. Doesn't do much now, implementing later.
Added icons to filter and on click listener to filter button
Merge branch 'master' of https://github.com/ghostling/Chirps into SearchFilterBar
Removed Filter Bar and Drawer from unrelated fragments
Moved implementation of search down into the search and filter bar and keeping it in MainActivity since filtering occurs in same activity.
Moved implementation of search down---somehow AndroidStudio didn't commit everything.
Moved implementation of filtering over to filter drawer. Stuff works!
Cleaned up some XMLs and removed Log messages that are not part of error catching.
Cleaned up more code and refactored most of MainActivity, Navigation and Filter Drawer. Remaining will be done once I modify the UI for the drawers.
Merge branch 'SearchFilterBar'
