Examples README: fix markup
MapCSS: Support 'image', 'icon-image', 'fill-image'

test.mapcss: 'in' link selector has been replaced by '>'
Rewrote parsing/compiling properties: simpler but more powerful
Example 4: simplify
load.sh: remove CONTEXT from warnings
pgmapcss_parse_string(): \n -> new line; documentation about escaped characters
Eval: min() and max() accept a list a (single) parameter
fix load.sh
pgmapcss_to: convert input to float (or default value, e.g. null)
Conditions: accept eval-statements as value
Eval::push(), concat(): when appending NULL, append empty string
osm2pgsql::objects_near(): cast distance to map units
Parse/Compile Condition: bugfix "!condition"
Parse Properties: Bugfix reading comments
load.sh: exit 1 when error occured
Examples: order by list in compile.sh
