[one-users] resize VM dialog is better, but there is a problem with VCPU

[Rolandas Naujikas]

Hi,

After 
http://dev.opennebula.org/projects/opennebula/repository/revisions/ba2bd837018a4d606e554b919359b74ecc888d9f 
resize dialog works better, but for VCPU there is logic error. In 
leftmost position VCPU value should be 1 at least, 0 - is not valid 
value. Maximum value should be also bigger 16 at least.

Also 0 value is not meaningful for CPU and MEMORY.

Regards, Rolandas

P.S. Of cause all those values could be entered manually.
