v2.3dev

Changes since v2.2:

• Reduced the initialization time of the search-based optimizer by 60% (resulting on a 30%-40% reduction in execution time overall)
• New data block optimizer (-do) that tries to look for data blocks that are repeated or can be optimized in other ways to save space
• Better support for sjasmplus
