v0.1.8-alpha Several Bugs

Created by: E3V3A

Hi I just tried this on a Samsung I9195 running stock 4.2.2. So to do this bug report quickly before I forget, I'll just list the issues. (I'll try to issues these as issues later.)

• "Tracking signal strength" icon still show red cross, when tracking
• [Menu] --> "Show Map" starts map centered on the sea outside Togo (Africa).
• [Menu] --> Preferences --> Icon Theme is not showing the current theme selection. All radio buttons are empty.
• Returning from "Show Map" using "top-left slider area" disables all tracking.
• Maps are not showing any cell towers (from OpenCellD)
• OpenCellID CSV file is empty (even after download)
• Exported CSV files contain many entries where only time stamp has changed. If only time-stamp has changed since last entry, an nothing else, then try to keep only the 1st and the last entries. This gives us a time-span to work with, without filling DB.
• Signal strength CSV is empty.
