In project setting page, plugin configurations were partially hidden if
value had more characters than the default number of characters
displayed in the text box.
For users who can edit the configurations, this is not an issue as they
can see the hidden part by moving the cursor in the text box. Users
which cannot edit the configurations, the field is disabled preventing
them to see the hidden part.
Fix it by making the text box wider if needed. This fix is not ideal
because if the value is really long, then the text box could be wider
than the screen size causing an horizontal scroll bar to appear.
An other option would have been to set the attribute "readonly" instead
of "disabled" which would allow users with no edit rights to see the
hidden part by putting the cursor in the text box. The problem is not
all the input controls used in the project page support setting the
readonly attribute so the code change would be more complex and
intrusive.
Since GWT UI is going away, go with the more simple and less intrusive
solution which is to make the text area wider when needed.
