What's new since 0.5.3?

• Windows helper is dynamically linked against libcurl again. Static linkage was causing more problems than it was fixing.
• Fix clonebundles support to ignore stream=v2 bundles.
• Ignore graft cinnabarclones when not grafting.
• Fixed a corner case where git cinnabar fsck would not skip files it was meant to skip and failed as a result.
