Fixed the section on traits.

Used most of what Jetryl said plus fix (and probably caused) a couple
of other errors as well.

 Intelligent units are very useful at the beginning of a campaign, as they can be quickly advanced into much needed higher level units. Later in the campaign, they are not quite so useful, and if you have plenty of high level units you may find yourself recalling units with more useful ''long-term'' traits." + _"

+Loyal units don't pay upkeep. Most units incur an upkeep cost at the end of every turn, which is equal to their level. Loyal units do not incur this cost.

+
+During campaigns, certain units may opt join the player's forces of their own volition.  These units are marked with the Loyal trait.  Although they may require payment to be recalled, they never incur any upkeep costs. This can make them invaluable during a long campaign, when gold is in short supply. This trait is never given to recruited units, so it may be unwise to dismiss them or send them to a foolish death." + _"

+Dexterous is a trait possessed only by Elves. The Elven people are known for their uncanny grace, and their great facility with the bow.  Some, however, are gifted with natural talent that exceeds their brethren.  These elves inflict an additional point of damage with each arrow to reflect this skill."
