core: Fix webzmachine include to be relative to the application
mod_base: Fix filter_capfirst to support i18n strings
core: Add 'default_colorspace' global option to set the default ImageMagick colorspace

In some ImageMagick versions, the default "sRGB" color space results
in resized images that are too dark.

The new default_colorspace global config setting allows to override
the color space with another one, like "RGB".

This solution was inspired on the similar fix in Typo3:
