* Fix: Do not share compiled instrument scripts among multiple engine
  channels (sampler parts) as this can lead to crashes and would allow the
  same global script variables to be accessible from multiple engine
  channels which would not be the expected behaviour by instrument script
  authors.

* Bumped version (2.2.0.svn5).

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