wrote documentation.

Made an accumulative mapping info table, this requires regular polling of new
data from the UCSC:
- Added:
  - install.sh: A preliminary installation script. Now only used for cron 
    entries.
  - Db.txt: Some loose documentation on how to make the new mapping table, to 
    be incorporated with an installation script.
  - src/UCSC_update.py: The update program, to be called from cron each day.
- Modified:
  - mutalyzer.conf: Added variables needed for the remote database of the UCSC.
  - Db.py: Rewritten nearly every SQL query to work with the new mapping table
    and to be able to download and import updates from the UCSC.
  - Config.py: Modifications to work with the new configuration variables.

Added:
- templates/sp.py: A webservice client template script.
- templates/download.html: The download page for developers.

Modified:
- Install.txt: Added more depenencies.

Switched to soaplib for the generation of a WSDL file. Webservices are now
published by adding functions to the MutalyzerService class in webservice.py,
each function should have a soapmethod decorator to specify the types.

Modified:
- handler.py: To work with soaplib.
- webservice.py: 
  - Put everything in a class to make soaplib able to generate a WSDL file.
  - Added the varInfo() webservice (calls the Variant_info script).
- index.py: Added documentation.
- Mutator.py: Added documentation.
- Web.py: Added documentation.
- Mutalyzer.py: Added generation of a new description in g. and c. notation.
- Db.py: Modified the get_Transcripts function to be able to work with
  overlapping and non-overlapping ranges.
