Added image support to verify password and username, deleted
alert-dialogs for the equal purpose. Added verification needed in order
to create account
Added pics for validation and refactored Registration.java, for now the
registration is done (without the db connection)
Updated Strings to solve merge issue
Merge remote-tracking branch 'origin/reg_pic_validation'

Conflicts:
	GitWarriorSolution/src/com/example/gitwarriorsolution/Registration.java
	
Fixed I hope!
