* Ref<> class: prevent compiler error if T == T_Base
  (due to method signature duplicate).

* Bumped version (2.1.1.svn55).

13     # The following is the libtool / shared library version. This doesn't have to
14     # do anything with the release version. It MUST conform to the following rules:
15     #
16     # 1. Start with version information of `0:0:0' for each libtool library.
17     # 2. Update the version information only immediately before a public release of
18     # your software. More frequent updates are unnecessary, and only guarantee
19     # that the current interface number gets larger faster.
20     # 3. If the library source code has changed at all since the last update, then
21     # increment revision (`c:r:a' becomes `c:r+1:a').
22     # 4. If any interfaces have been added, removed, or changed since the last update,
23     # increment current, and set revision to 0.
24     # 5. If any interfaces have been added since the last public release, then increment
25     # age.
26     # 6. If any interfaces have been removed since the last public release, then set age
27     # to 0.
