Whitelist address for creating proposals on TezDomDAO

[EightRice]

To avoid spam in the initial phase of their governance, Tezos Domains is kindly requesting that we only allow proposals on their DAO to be created by one single address: tz1TG2bxjvmRMQakt8KVQ5S6CyLzMuSHx2qF

Work to be done:

In the TezDomDAO only display the button to create a proposal if the address matches the hardcoded one.
