fixed spreading of the shader in twirl
Added space between name and category (for nodebrowser).
Output of HTMLTexture node should less likely be black/zero/nil when changing URL/Content.
The HTMLTexture node will now hold on to previously computed output values.

Texture/DOM/Document Size will stay the same until a new page is fully loaded.
Fixed regression regarding auto-size of texture when content changes.
FillDirList now reports correct filecount when "Include Subdirs" is enabled
Fixed namespace issue in CEF XmlReader.
The IsLoading output of the HTMLTexture node will stay true as long as

* CEF reports that it is loading content
* DOM was not retrieved yet
* Auto-size is enabled and document size wasn't retrieved yet
HTMLTexture fine tuning

* When switching a texture from degraded to non-degraded do the upload immediately (to avoid black textures)
* As long as the renderer reports that it is in the loading state do not touch the DOM/Document Size outputs
* A renderer will now also be in the is loading state if a texture is still degraded (waits for paint call of CEF)
* When auto size is enabled tell the textures immediately about it to reduce delay of texture updates
IsLoading output of HTMLTexture node will stay true until a texture is not dirty anymore.
added "invert" tag to Complement (Color)
helppatch fixes
added repeat & resample to the tag list of select nodes
refactored/grouped patches now popup under mouse-cursor when opened for the first time
alternative opening of editor is now on shift+click (was on ctrl+click where it conflicted with adding node to selection). fixes #645
vectors and matrices implement now IEquatable and IComaparable for linq pleasure. fixes #588
Merge branch 'develop' of github.com:vvvv/vvvv into develop
added LengthSquared to vectors, faster compare. adds to #588
removed unnecessary Math.Abs, minor performance improvement
Revert "iobox now defaults to min/max = 0 which means endless (in endless mode). in slidermode min/max need to be set to meaningful values in order to work"

This reverts commits 4223c8d0ff4918731f328c9525bd9732138fc3f1, b8fdcd139a1bc59c7f6ad8b38b682eb5c8188cfd and 2d709f4f0cb7031792b8d2f57e296d34d48126e5
