Appended missing newline characters at the end of multiple XML definition files to improve formatting consistency and prevent potential parsing issues.

Introduced FCP_Legion_Enlistment_Options.xml to define enlistment, missions, salary, provisions, storage, work, bounty, resign, and reinforcement options for Caesar's Legion. Enabled Legion enlistment in FCP_Legion.xml by uncommenting and configuring the relevant mod extension.
