remove duplicate matches for comparison

[omniomi]

Resolves #54. Comparison operators were covered twice:

<dict>	
	<key>match</key>	
	<string>(?&lt;!\w)-([ci]?[lg][te]|eq|ne)</string>	
	<key>name</key>	
	<string>keyword.operator.logical.powershell</string>	
</dict>

and

<dict>
	<key>match</key>
	<string>(?&lt;!\w)-(?i:[ic]?(?:eq|ne|[gl][te]|(?:not)?(?:like|match|contains|in)|replace))(?!\p{L})</string>
	<key>name</key>
	<string>keyword.operator.comparison.powershell</string>
</dict>

Removed the less complete of the duplicates:
