Previously if no language was specified, then illegal args would be passed to pygments, for example `pygments -l -fhtml`, which would result in pygments printing an error.
I could be wrong here, but it looks to me like .Site.Social.facebook is used in tpl/template_embedded.go, but the variable is never set. I've added a line to initializeSiteInfo to map the info from config into this variable.
In particular, RawContent() excludes the metadata header.
This is necessary in the use case of embedding remarkjs.com slides, as it needs
the unprocessed Markdown content to generate the slides.
`where` template function's internal condition check function always
returns `false` when a target value doesn't exist or it's nil value but
this behavior makes it difficult to filter values which doesn't have a
particular parameter.
To solve it, this adds nil value comparison to the function.
`where Values ".Param.key" nil` like clause can be used for the case
above.
Only "=", "==", "eq", "!=", "<>", "ne" operators are allowed to be used
with `nil`. If an other operator is passed with `nil`, the condition
check function returns `false` like before.
Fix#1232
There have been some changes to the ´helpers.GetThemesDirPath()´ so it now returns an empty string when no theme.
This is correct, but it broke the watch service (at lest on OSX), as `strings.HasPrefix("", "somestring") evaluates to true somehow, and content changes are incorrectly branded as static.
There are other issues in there, but that will come later ...
See #1236
Reduce duplication (`x + FilePathSeparator + y` a few lines away from `filepath.Join(x, y)`) and add a `GetThemeDir()` function to get the current theme's directory.
Also add a comment complaining about the `GetThemesDirPath()` function, which doesn't seem to do what its name would suggest. This might be a candidate for deprecation?
Even as a copy at the end is needed, this consumes way less memory on Go 1.4.2:

This commit replaces the regexp driven `replaceShortcodeTokens` with a handwritten one.
It wasnt't possible to handle the p-tags case without breaking performance.
This fix actually improves in that area:

Fixes#1148
Where `first` will return the first N items of a rangeable list,
`after` will return all items after the Nth item.
This allows the user to do something with the first N items and
something different with the remaining items after N.
