add: rapporter.net to the list of online frameworks

Please note that I had some difficulties with running `make`, so I updated the html and README files manually:

```
[~/projects/webservices]% make
Rscript -e 'library(ctv); ctv2html("WebTechnologies.ctv")'
Loading required package: XML
Loading required package: methods
Error: XML content does not seem to be XML: 'WebTechnologies.ctv'
Execution halted
Makefile:7: recipe for target 'dorstuff' failed
make: *** [dorstuff] Error 1
```

I would be extremely happy to see this pull request merged, please let me know how I should improve it. Thanks for maintaining the CRAN Task View!
