redeclipse.sh functions for bash and sh

[freezurbern]

I couldn't get redeclipse.sh to work on my Ubuntu system, it gave:

./redeclipse.sh: 4: ./redeclipse.sh: function: not found
./redeclipse.sh: 6: ./redeclipse.sh: Syntax error: "}" unexpected

Using

bash redeclipse.sh

doesn't cause problems with the functions, though.
So I found StackOverflow link about functions, which appears to fix the issue when the functions are defined as

NAME () { }

Another issue that could be fixed at the same time is to make sure the

/home/USER/.redeclipse/cache/devel/install.sh

file is set to executable by the user
