Fix for HTC Pinyin input method

HTC does not do beginBatchEdit/endBatchEdit when committing text.
We implement the commit in two steps: first set the text, then move
the cursor. To avoid sending an updateSelection for the intermediate state,
we need to block updates when we set the text in the editor.

Use camel case in PKCS#12 function

This makes it follow the coding style, which says to camel case acronyms too,
and makes it consistent with the rest of the class.
