Replace :hwvirtext with :hwvirtex

`:hwvirtext` isn't an attribute accepted by `modifyvm`.
Remove rel_path causes issues on windows across drives.

Given
	PWD is z:/src/gendev
	RUBY is installed in C:/Ruby193
	path1  = veewee/iso/sol-10-u11-ga-x86-dvd.iso
	path2  = Z:/src/gendev

When
	I run veewee vbox build <definition>
Then
	 I get the following error.

	C:/Ruby193/lib/ruby/1.9.1/pathname.rb:465:in `relative_path_from': different prefix: "" and "Z:/src/gendev" (ArgumentError)
	        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/veewee-0.3.12/lib/veewee/provider/core/helper/iso.rb:116:in `verify_iso'
	        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/veewee-0.3.12/lib/veewee/provider/core/box/build.rb:37:in `build'

Since both a relative and absolute paths should work with curl, md5, and shasum there should be a need to validate a relative path to the iso.

Improve CentOS 5.10 templates: Do not remove wireless-tools package

The wireless-tools package hosts the libiw.so.28 shared library that is used by system utilities such as iwconfig. Removing libiw.so.28 causes error messages during system startup when network interfaces are brought up ("iwconfig: error while loading shared libraries: [...]").

FreeBSD 10.0 RELEASE template

This template boots mfsbsd, which is used to install a minimal base
system onto the disk. The advantages of mfsbsd is that it is
significantly smaller than FreeBSD's disc1 ISO, and already handles many
of the install tasks that the install.sh script of previous FreeBSD
templates would handle.
