_profile: Major cleanup; Add "umask"; Remove "LC_CTYPE"

* Major cleanup:
  - Re-organize the settings
  - Some style/comments updates
  - New functions: "_exists()" and "_running()"
  - Remove "gpg-agent --daemon"
  - Remove "OSFONTDIR"
* Add "umask" to "027" to be more private!
* Add "LC_MONETARY=zh_CN.UTF-8"
* Remove "LC_CTYPE", which affects the behaviors of FontConfig!
  (see below note)

NOTE:
With "LC_CTYPE=zh_CN.UTF-8", a Chinese font (or a font with Chinese
language support) is always preprended to the generic font families
(i.e., serif, sans-serif, monospace), which overrides the
<alias><prefer> configurations.
It is also tested that Fcitx works OK without "LC_CTYPE=zh_CN.UTF-8"
