Deprecate replace and contains methods

[elharo]

New feature, improvement proposal

replace(String text, String repl, String with) text.replace(repl, with) Since Java 1.5. String.replace replaces all occurrences (despite the name not being replaceAll, which implies Regex).
replace(String text, char repl, char with) text.replace(repl, with) Since Java 1.5. Replaces all occurrences of the char.
contains(String str, String searchStr) str.contains(searchStr) Since Java 1.5.
