Fix Windows bug for pom name with space.

In Windows if there is a space in the pom.xml's name it causes the plugin to fail to generate a report xml. The single-line patch fixes the bug for Windows and it continues to work on Unix systems.

Including the codenarc-maven-plugin in a pom with spaces in the name (e.g. <name>Test Name</name>) will generate the following error:
```

     [java]     -basedir=<DIR>
     [java]     at org.codenarc.CodeNarc.main(CodeNarc.groovy:109)
     [java]         The base (root) directory for the source code to be analyzed.
     [java]         Defaults to the current directory (".").
     [java]     -includes=<PATTERNS>
     [java]         The comma-separated list of Ant-style file patterns specifying files that must
     [java]         be included. Defaults to "**/*.groovy".
     [java]     -excludes=<PATTERNS>
     [java]         The comma-separated list of Ant-style file patterns specifying files that must
     [java]         be excluded. No files are excluded when omitted.
     [java]     -rulesetfiles=<FILENAMES>
     [java]         The path to the Groovy or XML RuleSet definition files, relative to the classpath.
     [java]         This can be a single file path, or multiple paths separated by commas.
     [java]         Defaults to "rulesets/basic.xml"
     [java]     -title=<REPORT TITLE>
     [java]         The title descriptive for this analysis; used in the output report(s). Optional.
     [java]     -report=<REPORT-TYPE[:FILENAME]>
     [java]         The definition of the report to produce. The option value is of the form
     [java]         TYPE[:FILENAME], where TYPE is "html", "text", "xml", or "console" and FILENAME is the filename (with
     [java]         optional path) of the output report filename. If the report filename is
     [java]         omitted, the default filename is used for the specified report type
     [java]         ("CodeNarcReport.html" for "html" and "CodeNarcXmlReport.xml" for "xml"). If no
     [java]         report option is specified, default to a single "html" report with the
     [java]         default filename.
     [java]     -help
