Couldn't you store some sort of hash of the key in each project allowing cut
and paste between any project. If the hashes don't match then decrypt it
and re-encrypt it (assuming the user has both passwords) and if the hashes
do match jst do it the way you are now.

So if the password leaks there is no easy way of changing it forcing you to
create a completely new project? Couldn't you just decrypt everything and
the re-encrypt with the new password?

While I don't have my crypto books here (left them in my dorm room) I'm
pretty sure that term is already used for things like PGPfone and related
technologies where you encrypt a steam of data.

In terms of security you seem to be missing a few things:
First, an algorithm that depends on no one knowing the algorithm for
security is never secure. An algorithm should only depend on the private
key being kept a secret for security.
Second, are you saying you created your own semetric encryption algorithm
and expect it to be just as secure as IDEA, twofish or any of the other
publicly known (some are free for use) algorithms?
Third, there is the cryptoAPI which most people consider secure using good
algorithms already so there is no reason to implament your own.
The reason I asked about PGP was for for its signing ability. You seem to
be using a symetric algorithm which doesn't allow for code signing. Code
signing would allow a developer to know who wrote a block of code and make
sure no one else modified it.
