verbose flag in svntools should be converted to boolean

[Neil Muller]

The verbose flag to the svn: commands is passed in as a string, but treated as a boolean when testing. This leads to the following recipes behaving identically:

<svn:checkout url="file:///home/neil/tmp/CTPUG/bitten-sprint/trac/test-svn"
        path="${path}" revision="${revision}" verbose="false" />

and

<svn:checkout url="file:///home/neil/tmp/CTPUG/bitten-sprint/trac/test-svn"
        path="${path}" revision="${revision}" verbose="true" />

and differing from the recipe excluding the verbose flag.

This is somewhat unexpected.

simple patch to verbose handling

[Neil Muller]

Simple patch to make verbose="False" work. This still accepts verbose="foo" as true, which should perhaps be flagged as an error.

Fixed in r847 and backported to 0.6.x in r848. Thanks for the patch!
