/** \brief Returns a vector of usable Compression Types
*
* Files can be compressed in various ways to decrease the size of the
* download. Therefore the Acquiremethods support a few compression types
* and some archives provide also a few different types. This option
* group exists to give the user the choice to prefer one type over the
* other (some compression types are very resource intensive - great if you
* have a limited download, bad if you have a really lowpowered hardware.)
*
* This method ensures that the defaults are set and checks at runtime
* if the type can be used. E.g. the current default is to prefer bzip2
* over lzma and gz - if the bzip2 binary is not available it has not much
* sense in downloading the bz2 file, therefore we will not return bz2 as
* a usable compression type. The availability is checked with the settings
* in the Dir::Bin group.
*
* \param Cached saves the result so we need to calculated it only once
* this parameter should only be used for testing purposes.

* The special word "environment" will be replaced with the long and the short
* code of the local settings and it will be insured that this will not add
* duplicates. So in an german local the setting "environment, de_DE, en, de"
* will result in "de_DE, de, en".
*
* Another special word is "none" which separates the preferred from all codes
* in this setting. So setting and method can be used to get codes the user want
* to see or to get all language codes APT (should) have Translations available.
