N95 Speed Camera Warning - scLib

I've created a single package containing the three libraries (appswitch, landmarks, locationrequester) that SpeedCam needs. The aim is to simplify installation by only having to sign and install one file rather than each of the three files individually. If you have previously installed appswitch, landmarks, locationrequester modules individually these will need to be removed before you instal scLib otherwise an update error will occur on installation.
