TIMOB-9141 BlackBerry: Fix merge problems

[jpl-mac]

Reviewers: DL + DC

Fix some issues coming from merges
Also modify the population of the functionMap so order won't be an issue anymore.

• Use a vector for the map
• use enum instead of defines for the PROP ids, will give a bit more robustness,
  particularly protect against duplicates in prop names and in values
  Also allows keeping the prop in alphabetical order

Changelog:

• Use vector for the functionMap, added a static initializer
• Changed the type of the first param of setPropertyValue to size_t to prevent compiler warning about signed/unsigned comparison
• Removed left over setTop(float) declaration
• use enum for N_PROP ids
• use props everywhere in setTiMappingProperties
• updated app.js to use title for button text
• Commented a call that doesn't compile on R4
• Removed icon assets from bar-descriptor that don't exist anymore

Tests:

• Built tibb lib for all 3 targets
• Built tibbtest for all 3 targets
• Validated that app.js still works as before and labels do get displayed
• Tested everything with R4 tools
