Mike has improved the performance of the view issue page by making the following changes:

• Caching user preferences, rather than fetching them. This is done on a LRU basis
• IssueSecuritySchemeManager now caches its schemes
• DefaultIssueLinkManager caches links on a LRU basis
• ProjectCache now has a getProjectByID method
• DefaultWorkflowSchemeManager now has a LRU cache

This reduces the number of SQL queries that are produced for a single view issue page.
