move config.assets.precompile into config/application.rb
Reduced memory leak problem in transactions by lazily updating AR objects with new transaction state. If AR object has a callback, the callback will be performed immediately (non-lazily) so the transaction still has to keep records with callbacks.
Added comments about the check_empty_arguments method which is called
for query methods in a where_clause. Also, modified the CHANGELOG entry
because it had false information and added tests.

reserve index name chars for internal rails operations

Some adapter (SQLite3) need to perform renaming operations to support
the rails DDL. These rename prefixes operate with prefixes. When an
index name already uses up the full space provieded by
`index_name_length` these internal operations will fail. This patch
introduces `allowed_index_name_length` which respects the amount of
characters used for internal operations. It will always be <=
`index_name_length` and every adapter can define how many characters
need to be reserved.

Renaming the check_empty_arguments method to something more descriptive.
The function is now called has_arguments? so that it's easier to tell
that it's just checking to see if the args are blank or not.
also rename indexes when a table or column is renamed

When a table or a column is renamed related indexes kept their name. This will lead to confusing names. This patch renames related indexes when a column or a table is renamed. Only indexes with names generated by rails will be renamed. Indexes with custom names will not be renamed.
