Type keywords are not used for arrays

Type keywords are not used when the type name is part of an array type.

Example input:
```java
String[] lemmatize(String[] toks, String[] tags);
```

Example output:
```c#
String[] Lemmatize(String[] toks, String[] tags);
```

Should be (note the capitalization):
```c#
string[] Lemmatize(string[] toks, string[] tags);
```
