Introduction variables for product name (#65)

In _config.yml two variables were introduced under "product" key:

- "name" for "syslog-ng Open Source Edition" 
- "short_name" for "syslog-ng OSE"

You can refer them in markdown as **{{ site.product.name }}** and **{{
site.product.short_name }}**, respectively.
Please use them if you have to refer to syslog-ng OSE. 
External link texts don't have to be adjusted.

All instances of "syslog-ng OSE", and "syslog-ng Open Source Edition"
texts were replaced with the variables above.
All instances of "syslog-ng" texts were replaced with short_name (where
it was applicable).

Possible known issue: see #61 , will fix title links in a separate PR.
