Incompatible changes

WebHare now calculates the dominant color for all images when they're stored into WHFS or WRD (or when WrapBlob is invoked with the extractdominantcolor option). All existing file/image records have been extended with a field 'dominantcolor' which will either be empty (unknown), a CSS color code (eg #123456) or 'transparent' (no dominant color)
All fsobjects, fssettings and wrd settings which contain an image will be converted in the background after you upgrade.
- To check on the progress of this conversion, run watch wh scandataprogress or wh scandataprogress
- To abort conversion (eg due to unexpected high load), delete all system:convertscandata tasks in monitor > managed tasks
- To restart conversion after aborting, run the kickstart script: wh run mod::system/scripts/runonce/kickstart_scandata_conversions.whscr. As this script needs to find the highest allocated settingid for WHFS and WRD, it may take a few minutes to run.

DecodeValue and DecodeHTML now remove all HTML tags from their input, instead of just entities and <br />
Resolve(STRING relativepath) resolves the specified path against the current library. Eg. Resolve("page.witty") will give you the mod::x/y/z/page.witty path for the file page.witty in the folder next to your current whlib.

Both URL history storage and redirect-on-404 are now enabled by default. You need to explicitly opt out of URL history
The URL history dialogs are now always available for published files, they no longer check for the URL history 'store' flag
The URL history now preserves any part following the /!/ separator
Siteprofiles <apply><to> rules support regular expressions in attributes pathregex, parentpathregex and siteregex. Regexes are tested case-insensitively, but be sure to anchor them.. you probably want ^/tmp/myfolder$/ and not just tmp/myfolder...

Simplify API2017 migration:
- ->GetType(STRING) now works on both API2017 and legacy schema objects. It will always return a API2017 WRDType! (legacy schemas still support calling GetType with an INTEGER parameter and will return a legacy wrdtype)
- The types member is now also available on legacy schema objects, but will always return API2017 WRDTypes.
