[Wiki update] Building Tvheadend - add dependency libcurl4-openssl-dev.
It looks like libcurl4-openssl-dev is a dependency to Tvheadend,
it should be added to the prerequisites in the Building page on the wiki.
I did follow the guide on a clean Ubuntu 12.04,
and needed to install the package as it seems to be not included with the build-essential.
Here's the link to the proper page https://www.lonelycoder.com/redmine/projects/tvheadend/wiki/Building.
You should consider deleting the Tvheadend_debian page on the wiki, it's indexed in Google so it is accessible.
