Because my home machine is pretty slow, I noticed a high demands of 
script. On one smaller test project ran over 24 minutes.

I've done in this script some optimizations:

1) Instead of starting sed using "find -exec sed" I used the "find | xargs 
sed". With xargs not run sed for each file, but one sed for multiple 
files.

2) Instead of starting sed for each replacement I'm using "-e" amassed 
more replacements to the single sed.

After this optimizations on the same small test project I'm got the same 
result in 2.5 minutes. Updated script pushed to git in hash 5fc3ba9a.
