seriously cleaned up the database stuff and added an updateBook method
messing with color changes for book selecting
selecting books works quite nicely (and doesn't look like crap)
commiting new db with filesizes hardcoded
okay.. selecting things *actually* works now
new filesize db entry
scrolling textview and some other stuff
deleted a commented line
Merge remote-tracking branch 'origin/master'

Conflicts:
	bookmix/src/main/assets/booksManager.db
	bookmix/src/main/java/com/cs252/bookmixer/bookmix/DatabaseHandler.java
deleted a commented line
wrong db
correct db
downloading actual books works
