Fix typos and grammar issues in README.
typo at Optimizer/block_pass.c
Fixed zend_optimizerplus.enable_file_override=1 compatibility with PHP-5.3

Closes #2
Fix typo
Avoid unnecessary code and change the type of accelerator_enabled

accelerator_enabled will always be true when accelerator_get_status
returns an array. Also the accelerator_enabled should be a boolean
and not a long
Avoid compilation of unsupported SHM backends

Renamed README into README.md

- Added zend_optimizerplus.load_comments configuration durective, so "Doc comments" may be always stored in SHM, but
restored only by applicaions that really need them.
- Added note, that zend_optimizerplus.save_comments is dangerous and may break applications and frameworks.
