[rfc][icedtea-web] Use File for cache directory instead of String

[Jie Kang]

Hello,

This patch changes the type of cacheDir from String to File.

This patch is a changeset on top of the patch "Allow cache directory to be changed during runtime" discussed here[1]. Both patches have been attached for convenience.

[1] http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2015-January/030316.html

Patch order:  HEAD -->> itw-change-cache-location -->> itw-cache-string-to-file


How does it look?


Regards,
