Added one of the GenBank upload functions as a webservice function.

Install.txt:
- Added a dependency.

wsgi.py:
- Updated the release date and version number.

webservice.py:
- Added the function sliceChromosomeByGene(), which is used to get a reference 
  sequence, given a gene name, organism and a length of flanking sequences.
- Added templates for other GenBank upload functions:
  - upLoadGenBankLocalFile()
  - upLoadGenBankRemoteFile()
  - sliceChromosome()

wsdl-viewer.xsl:
- Modified the template to use stable internal links, instead of randomly
  generated ones. This is only an example, more links should be treated like
  this.
