Add the ability to reference other DLLs

[ha11owed]

I have added the ability to reference other DLLs and .xaml ResourceDictionaries. This can be useful if you have your custom WPF controls or Styles and want to reference them in the .xaml documents.

for example this allows me to work with a .xaml like below by starting kaxaml with the following command line parameters: -i C:\pathto\MyControls.WPF.dll -i C:\pathto\ResDict.xaml. Previously this would have failed. Adding my DLL to the kaxaml installation folder would have solved the problem of recognizing the namespace, but it would still have failed when trying to use the StaticResources:

<StackPanel xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
           xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
           xmlns:myControls="clr-namespace:MyControls.WPF.Controls.myControls;assembly=MyControls.WPF">
  <myControls:MyCustomControl ShowIdentifier="false" DatabaseId="0" ViewTemplate="{StaticResource HexTextBlock}" />
  <myControls:MyCustomControl ShowIdentifier="false" DatabaseId="2" ViewTemplate="{StaticResource VolumeMeter160to60}" />
  <myControls:MyCustomControl ShowIdentifier="false" DatabaseId="1" ViewTemplate="{StaticResource VolumeMeter160to60PeakRider}" />
  <myControls:MyCustomControl ShowIdentifier="false" DatabaseId="0" ViewTemplate="{StaticResource VolumeMeter160to60}" />

  <StackPanel Orientation="Horizontal">
    <TextBlock Text="Some horizontal values:" />
    <myControls:MyCustomControl ShowIdentifier="false" DatabaseId="2" ViewTemplate="{StaticResource SimpleFloatTextBlock}" />
    <myControls:MyCustomControl ShowIdentifier="false" DatabaseId="1" ViewTemplate="{StaticResource FloatTextBlock}" Index="1" />
    <myControls:MyCustomControl ShowIdentifier="false" DatabaseId="0" ViewTemplate="{StaticResource SimpleFloatTextBlock}" Index="2" />
  </StackPanel>
</StackPanel>
