Update popups to use full screen modal

[dreikanter]

Forms to update:

• New Transfer
• New Reconcile
• New Category
• New Account

Requirements:

• Reuse existing fields sequence: http://boodka-demo.herokuapp.com
• Layout should be responsive (iPhone 5 screen size compatibility required).
• For all forms replace "Memo" with one-line text field (input type=text).

Details:

• Use SASS.
• Use bower to maintain dependencies.
• Use gulp to build the frontend assets.
• Don't include Bootstrap and other dependencies into the repository.
• Use linters to validate/maintain code style (either CLI or Sublime plugins):
  • http://eslint.org
  • https://github.com/sasstools/sass-lint
  • https://github.com/CSSLint/csslint/wiki/Command-line-interface
