#1349 Incomplete *.alpha in Portugese translation

[Jakub Wilk]

In gentext/locale/pt.xml, lowercase.alpha and uppercase.alpha include only ASCII characters, but Portugese words use also many accented characters. Please change it to:

<l:gentext key="lowercase.alpha" text="aáàâãbcçdeéêfghiíjklmnoóôõpqrstuúvwxyz"/>
<l:gentext key="uppercase.alpha" text="AÁÀÂÃBCÇDEÉÊFGHIÍJKLMNOÓÔÕPQRSTUÚVWXYZ"/>
