Bug 17696: Add 2 missing periods in opac-suggestions.tt

Problem:

- two missing trailing periods in template

Test plan:

- configure MaxOpenSuggestions with a low limit (e.g. 1)
- visit opac-suggestions.pl?op=add, login if necessary
- note that the period is missing from the second sentence of the leading paragraph under the "Enter a new purchase suggestion" heading
- continue to submit suggestions until you've reached the MaxOpenSuggestions limit
- observe the missing period in the "TooManySuggestionsText" paragraph
- apply patch
- revisit opac-suggestions.pl?op=add
- note that the period is now present in the second sentence of the leading paragraph under the "Enter a new purchase suggestion" heading
- note that the period is also present at the end of the "TooManySuggestionsText" paragraph
