OSGi Provide-Capability fields are wrong

[Mark Raynsford]

They're currently declared as (for example):

<Provide-Capability>
  com.io7m.jsycamore.theme.name;type:String=Stride
</Provide-Capability>

But should be:

<Provide-Capability>
  com.io7m.jsycamore.theme;name:String=Stride
</Provide-Capability>

This is an unfortunate typo that was copied to each of the provided themes...
